* itpp/base/array.h, itpp/base/mat.cpp, itpp/base/mat.h,
itpp/base/vec.cpp, itpp/base/vec.h: Improved the consistency of
alloc(), free() and set_size() methods in Array, Mat and Vec
classes. Further cosmetic changes of separating class interfaces
from their implementation in these base classes.

* itpp/base/mat.cpp, itpp/base/mat.h, itpp/base/vec.cpp,
itpp/base/vec.h: Cosmetic changes in order to separate class
interfaces from implementation. BTW, private init() function
replaced with initialisation list.
* doc/Makefile.am, itpp/base/algebra/Makefile.am,
itpp/base/algebra/sources.mk, itpp/base/bessel/Makefile.am,
itpp/base/bessel/sources.mk: Removed "lapack.h" and
"bessel_internal.h" from the list of installed headers. BTW,
cleaned up the dependency list in the documentation Makefile.

itpp/signal/fastica.cpp, itpp/signal/freq_filt.h,
itpp/srccode/vqtrain.cpp, itpp/stat/misc_stat.h,
itpp/stat/sources.mk: Minimum and maximum functions moved back to
the "base" module, because they are widely used in all modules.

tests/schur_test.cpp, tests/source_test.cpp, tests/stat_test.cpp,
tests/svd_test.cpp: Moved the rest of statistical routines from
"base/stat.*" to the "stat" module. Because these functions are
commonly used in all other mudules, the "stat" module is now
compulsory as the "base" one.
2006-12-20 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp: Fixed a minor problem in merging process
of tap Doppler spectra. BTW, improved the related conditional

Small changes to the documentation to allow the
vector and matrix classes to be visible from the
Modules section (helps new users)
2006-12-12 Conrad Sanderson <[email protected]>
* itpp/base/vec.h, itpp/base/vec.cpp: Added vector versions
of elem_mult_inplace(), elem_mult_out(), elem_div_out(),
elem_mult_sum() and elem_div_sum().
See the 2006-12-07 entry by Conrad for more information.

Added some missing function checks to configure.ac, which should
improve the portability of the library on various platforms.
* itpp/comm/channel.cpp, tests/channel_test.ref: Fixed a bug that
resulted in different output samples of the IFFT fading generator
on SPARC Solaris using GCC 3.4.5, than the ones obtained in other
enviroments. The problem was probably caused by a different order
of calculating the random arguments of the concat() function. Do
not know if this is a bug of GCC for Solaris, or it is not fully
specified behaviour in C/C++ standards.
2006-12-07 Conrad Sanderson <[email protected]>
* itpp/base/mat.h, itpp/base/mat.cpp: Added elem_mult_inplace(),
elem_mult_out(), elem_div_out(), elem_mult_sum() and elem_div_sum().
Descriptions:
elem_mult_inplace() is a fast version of B = elem_mult(A,B).
elem_mult_out() and elem_div_out(): element-wise multiplication
and division of matrices, respectively, with the result stored
in a matrix given as an argument.
elem_mult_sum() and elem_div_sum(): element-wise multiplication
and division of matrices, followed by summation of the resultant
elements.
* itpp/base/matfunc.h, itpp/base/matfunc.cpp: Added sumsum(),
which is a fast version of sum(sum(A)) (i.e. calculates the
total of all elements in a matrix).
* itpp/stat/mog_diag.h: Fixed a small typo.

* itpp/comm/modulator_nd.*: Minor code readability and
efficiency improvements
2006-11-10 Adam Piatyszek <[email protected]>
* itpp/srccode/gmm.h: Fixed bug [1570388] by adding a warning
message to `get_no_mixtures()' function saying that it is
deprecated and that `get_no_gaussians()' should be used instead
(merged rev. 713:714 from itpp-3-10 branch).
* itpp/comm/channel.cpp: Fixed default initialisations and checks
in particular fading related methods (set_no_frequencies(),
set_filter_length(), etc.).
(merged rev. 657:716 from the channel-update branch)
2006-11-09 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp: Removed wrong and unnecessary checks for
positive time offsets.
(merged rev. 657:716 from the channel-update branch)
2006-11-07 Adam Piatyszek <[email protected]>
* itpp/comm/channel.h: Minor documentation changes.
(merged rev. 657:716 from the channel-update branch)
* itpp/comm/channel.cpp, itpp/comm/channel.h: The channel
discretization function improved and moved to the TDL_Channel
class. An additional parameter `sampling_time' is required when
setting the channel profile using the Channel_Specification
object.
(merged rev. 657:716 from the channel-update branch)
* itpp/comm/channel.cpp: Simplified GaussI and GaussII Doppler
spectra calculations.
(merged rev. 657:716 from the channel-update branch)
2006-11-06 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp, itpp/comm/channel.h: Improved interface
for setting various fading parameters in Channel_Specification and
TDL_Channel classes. Relative Doppler is set to 0.7 by default,
when only relative power (Rice factors) is specified. BTW, the
documentation was revised.
(merged rev. 657:716 from the channel-update branch)
* itpp/comm/channel.cpp, tests/channel_test.ref: Fixed a bug in
LOS process generation in the Independent and Static fading
generators.
(merged rev. 657:716 from the channel-update branch)
* tests/channel_test.cpp, tests/channel_test.ref,
itpp/comm/channel.cpp, itpp/comm/channel.h, tests/Makefile.am:
Fading generators inheritance model redesigned. Now there are
three types of fading: Independent, Static and Correlated. The
Correlated fading can be generated using Rice (MEDS), FIR or IFFT
methods. A basic test program of channel classes added.
(merged rev. 657:716 from the channel-update branch)
2006-11-02 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp, itpp/comm/channel.h: A set of new
features and improvements added:
- `Rice' keyword removed from the DOPPLER_SPECTRUM enum; `Jakes'
or `Classic' should be used instead.
- Explicit selection of a fading type implemented. When fading_type
is equal to `Correlated', non-zero normalised Doppler needs to be
specified. The default fading type is set to `Independent'.
- Better implementation of independent fading generator.
- Added missing initialisations of time_offset in FIR and IFFT
fading generators.
- Removed the `decimation_factor' parameter, since its use was bad
in a few places.
(merged rev. 657:716 from the channel-update branch)
* itpp/comm/rec_syst_conv_code.cpp: To avoid code duplication, the
local `com_logmap()' function replaced with its safer
implementation `log_add()' from "itpp/base/logexpfunc.h". Thanks
to Erik G. Larsson for pointing this out.
2006-11-01 Adam Piatyszek <[email protected]>
* AUTHORS, configure.ac, doc/local/authors.doc,
itpp/base/logexpfunc.h, itpp/config_msvc.h: New `log_add()'

expression: log(exp(log_a) + exp(log_b)). Thanks to Conrad
Sanderson for his patches.

tests/convcode_test.cpp: Function `needed_bits()' marked as
deprecated, because its name was a bit misleading (see bug
[1480535]). Instead of it the following two functions were added:
`int2bits()' and `levels2bits()'. The first one returns the number
of beed required for representing an unsigned integer, e.g.
"int2bits(0) = 1", "int2bits(2) = 2". The latter one returns the
number of bits to code a certain, positive number of values
(levels). For example: "levels2bits(1) = 1", "levels2bits(2) = 1".

* IT++ 3.10.6 released (SVN tag: release-3-10-6)
* NEWS: Updated to reflect recent changes (merged rev. 679:681
from itpp-3-10 branch).
* itpp/Makefile.am: Fixed bug [1576333]. The problem with
undefined non-weak symbols has been solved according to the
solution from Section 7.3.5 "Libtool Convenience Libraries" of
automake manual. Thanks to Ed Hill for reporting this bug and his
work on RPM package for Fedora Core (merged rev. 676:677 from
itpp-3-10 branch).
2006-10-14 Erik G. Larsson <[email protected]>
* doc/tutorial/src/mimoconv.doc: Improvement to tutorial example
* doc/local/installation.doc: Minor update

error in ND_UQAM
2006-10-13 Erik G. Larsson <[email protected]>
* doc/tutorial/src/mimoconv.doc: Update to reflect the change in
LLR convention.
2006-10-12 Erik G. Larsson <[email protected]>
* itpp/comm/llr.h, itpp/comm/modulator_nd.*: Changed the
definition of LLRs from log(P(b=1)/P(b=0)) to log(P(b=0)/P(b=1))
in the LLR and Modulator_ND classes. This was done to conform to
the conventions in the scalar modulator class. (Note the interface
change.)
* doc/tutorial/tutorial.doc, doc/tutorial/mimoconv.doc,
doc/tutorial/src/mimoconv.cpp: Added first version of new MIMO
tutorial.
2006-10-08 Adam Piatyszek <[email protected]>
* itpp/comm/modulator.h: Additional check added to prevent
improper initialisation of symbols and bit2symbols in the
Modulator class. This fix is related to bug [1572807].
2006-10-06 Adam Piatyszek <[email protected]>
* itpp/base/itassert.cpp, itpp/base/itassert.h: Implemented
feature request [1569867]. Now, it_assert(), it_warning() and
it_error() functions can use stream operators like `<<' or
`std::endl' in a concatenation with strings, e.g.
`it_error("Wrong value x = " << oct << x)'. Thanks to George
Jongren for submitting a patch.
2006-09-18 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp: Removed redundant concat() functions in
Gauss Doppler spectra's initialisation.
(merged rev. 657:716 from the channel-update branch)
* itpp/comm/channel.cpp, itpp/comm/channel.h: Implemented missing
"Gauss I" and "Gauss II" Doppler spectra required by a few COST207
channel models. These Gaussian spectra are only available in the
Rice_Fading_Generator class
(merged rev. 657:716 from the channel-update branch)
2006-09-05 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp, itpp/comm/channel.h: Added additional
assertion checks for undersampled cases in Channel_Specification's
discretize() function. It is now possible to discretize the
channel with too low sampling frequency, but only if all taps
except the first one use the default Jakes Doppler spectrum and
has no LOS (Rice) parameters.
(merged rev. 657:716 from the channel-update branch)
* itpp/comm/channel.cpp, itpp/comm/channel.h: Fixed improper
initialisation of los_power and los_dopp variables in TDL_Channel
class.
(merged rev. 657:716 from the channel-update branch)
2006-09-04 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp, itpp/comm/channel.h: Implemented
exponential channel profile generation function. Cleaned up the
interface of various fading generator classes:
- only one generate() function with additional default parameter
decimation_factor (instead of misleading name upsampling_factor)
- implemented add_LOS() function in the base class, which is
reused by the child classes
- global jake_filter() function moved into FIR_Fading_Generator
class
- all get_*() functions changed to the const ones
- base class `init_flag' is now set in the initialisation list of
the constructor.
(merged rev. 657:716 from the channel-update branch)
2006-09-03 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp, itpp/comm/channel.h:
Channel_Specification and TDL_Channel classes extended with
support of LOS (Rice) fading for any tap. Doppler spectrum of type
`Rice' is now merged with `Jakes' or `Classic', since the
generation method is the same. To obtain `Rice' spectrum
relative_power and relative_doppler needs to be defined for a
certain tap(s).
(merged rev. 657:716 from the channel-update branch)
2006-09-03 Erik G. Larsson <[email protected]>
* doc/tutorial/matlab_itpp.doc: Expanded the Matlab/IT++
conversion table.
2006-09-02 Erik G. Larsson <[email protected]>
* itpp/comm/modulator.h, modulator_nd.h, modulator_nd.cpp:
Documentation update and improvement of range checking in
interface.
2006-09-01 Adam Piatyszek <[email protected]>
* Makefile.am: Added new `snapshot', `snapshot-src' and
`snapshot-html' targets for automatic creation of snapshot
distribution packages.
2006-08-31 Tony Ottosson <[email protected]>
* doc/tutorial/itfile.doc: Fixed small documentation bug.
2006-08-24 Adam Piatyszek <[email protected]>
* itpp/base/svec.h: Fixed bug [1545798]. Sparse vectors are now
correctly compared using `==' operator. Thanks to Timo for
reporting this bug.
2006-08-22 Adam Piatyszek <[email protected]>
* itpp/comm/modulator.cpp, itpp/comm/modulator.h: Added simplified
versions of demodulate_soft_bits() functions to the QPSK modulator
class. This gave about 40% improvement in the demodulation
performance.
2006-08-21 Adam Piatyszek <[email protected]>
* itpp/comm/modulator.h, tests/modulator_test.cpp: Added
deprecated demodulate_soft_bits_approx() functions with a warning
message for backward compatibility reasons. Besides, the default
soft demodulation method of demodulate_soft_bits() functions is
now log-MAP.
2006-08-19 Adam Piatyszek <[email protected]>
* itpp/comm/channel.cpp: Fixed bug [1542064]. The problem was that
the index in the tap_doppler_spectrum array in the
TDL_Channel::init() function could go out of bounds, if the
TDL_Channel class was used with two different channel profile
lengths. Thanks to Jordy Potman for reporting this bug and
providing a patch with a solution (merged rev. 645:646 from
itpp-3-10 branch).
* itpp/comm/modulator.cpp, itpp/comm/modulator.h,
tests/modulator_test.cpp: Further redesign of 1D and 2D modulator
classes. From now, there is only one templated base class
Modulator, which can handle 1D (real) and 2D (complex)
constellations. BPSK and PAM modulators are split into:
BPSK_c/PAM_c classes which use complex valued interface but only
real part of the signal is used, and BPSK/PAM classes that have
real valued interface. Besides, demodulate_soft_bits() functions
use additional parameter "method" to switch between Log-MAP or
approximate demodulation algorithm.
* itpp/base/elmatfunc.cpp, itpp/base/elmatfunc.h: Reverted the
previous interface of binomial functions. "double binom()" defined
for higher range of calculated results.
2006-08-19 Erik G. Larsson <[email protected]>
* itpp/comm/egolay.cpp: Included "converters.h".
2006-08-19 Adam Piatyszek <[email protected]>
* itpp/comm/egolay.cpp: Minor fix - "(int)floor()" replaced with
"floor_i()".
2006-08-18 Adam Piatyszek <[email protected]>
* itpp/base/elmatfunc.cpp, itpp/base/elmatfunc.h,
itpp/base/itmisc.cpp, itpp/base/itmisc.h: Fixed bug [1542482]. Now
binom(n, k) works properly. "double binom(int, int)" was
redundant, because the result of this function was always
integral. Therefore it was replaced with "int binom(int, int)".
BTW, moved fact(), binom(), log_binom() and gcd() functions from
itmisc.{cpp,h} to elmatfunc.{cpp,h}.
2006-08-16 Adam Piatyszek <[email protected]>
* tests/modulator_test.cpp, tests/modulator_test.ref: Updated
tests of 1D and 2D modulators due to the recent redesign of these
classes.
* doc/local/index.doc.in: Minor fix ("CVS" -> "SVN") (merged rev.
633:634 from itpp-3-10 branch).
* doc/doxygen_html.cfg.in: Include files and file list now contain
a relative path.
* itpp/comm/modulator.cpp, itpp/comm/modulator.h,
tests/modulator_test.cpp, tests/modulator_test.ref,
tests/pulse_shape_test.ref: Major redesign of one- and
two-dimensional modulator classes. Modulator_2D is now a base
class for QAM, PSK and PAM modulators. Moreover, QPSK and PSK
inherits from the PSK class. Please note that input signal for
Modulator_2D has now slightly different meaning. BTW, improper
definition of QPSK constellation is fixed (it was in fact 4-QAM
modulator previously).
* itpp/comm/bch.cpp, itpp/comm/egolay.cpp: Added missing include
files.
* doc/doxygen_html.cfg.in, doc/local/itpp_header.html: Minor fixes
in Doxygen config file.

from itpp-3-10 branch).
2006-08-12 Erik G. Larsson <[email protected]>
* itpp/comm/modulator_nd.{cpp,h}, itpp/comm/llr.{cpp,h},
tests/modulator_nd_test.ref, tests/llr_test.ref: Documentation
updates and cosmetic changes.
2006-08-11 Adam Piatyszek <[email protected]>
* doc/local/verification.doc: Updated with Windows tests (merged
rev. 612:613 from itpp-3-10 branch).
* itpp/base/parser.cpp: Minor fix of uninitialised bool variable.
* itpp/base/itmisc.h, itpp/base/random.h: Replaced deprecated
hypot(x, y) function with std::sqrt(x*x + y*y) calculation. BTW,
macro definition M_2PI replaced with a global constant m_2pi.
* itpp/base/mat.cpp, itpp/base/mat.h: Fixed a minor problem of
uninitialised matrix elements, when parsing values from a string
literal.
* itpp/signal/sigfun.cpp: Fixed bug [1538210], caused by
uninitialised variable `m2' used for covariance calculation.
Thanks to Max Moorkamp for reporting this bug.
* itpp/comm/modulator.cpp, itpp/comm/modulator.h,
tests/modulator_test.ref: Further cosmetic changes and minor fixes
in QPSK, PSK and QAM modulator classes. Use the new trunc_log()
function when calculating log-likelihood ratio. Reference data for
test program updated accordingly.
2006-08-10 Adam Piatyszek <[email protected]>
* itpp/comm/modulator.cpp, itpp/comm/modulator.h: Minor fixes in
BPSK and PAM modulator classes. Now use the new trunc_log()
function when calculating log-likelihood ratio.
2006-08-10 Erik G. Larsson <[email protected]>
* itpp/comm/rec_syst_conv_code.cpp: Now use the new trunc_exp()
and trunc_log() functions instead of macros.
2006-08-10 Adam Piatyszek <[email protected]>
* itpp/comm/modulator.cpp, itpp/comm/modulator.h: Modulator_1d and
Modulator_2d classes revised with respect to bug [1456235]. The
precision problems for high SNR have been solved by using the
trunc_log() function recently defined in "logexpfunc.h" file.
Thanks to Erik for his help in solving this problem. This fix
closes the bug report [1456235].
* itpp/base/logexpfunc.h: Added special truncated versions of
log() and exp() functions, which might be used instead of the
macros in modulator.cpp and rec_syst_conv_code.cpp (more stable
and portable solution). These functions check if floating-point
arithmetic is conforming to IEC 559 standard. If not, standard
log()/exp() functions are used.
2006-08-09 Erik G. Larsson <[email protected]>
* itpp/comm/rec_syst_conv_code.cpp: Changed functions into macros
to handle truncation of argument of exp() and log().
* itpp/comm/modulator.cpp, itpp/comm/modulator.h: Documentation
updates and polishing of code.
2006-08-09 Adam Piatyszek <[email protected]>
* configure.ac, doc/Makefile.am, Makefile.am: Added `upload',
`upload-src' and `upload-html' targets for automatic upload
tarballs into SourceForge ftp server.
2006-08-08 Adam Piatyszek <[email protected]>
* itpp/base/parser.cpp: Fixed a minor bug in get<int>() function
caused by too early execution of it_assert() check function.
* itpp/base/mat.cpp, itpp/base/mat.h, itpp/base/vec.cpp: Fixed a
minor bug in string parsing functions that prevented
initialisation of a vector/matrix with an empty string "".
2006-08-08 Erik G. Larsson <[email protected]>
* itpp/comm/rec_syst_conv_code.cpp, itpp/comm/rec_syst_conv_code.h:
Added floating point range tests when using exponential and
logarithm functions to avoid numerical errors at high SNR in
map_decode(), to address bug [1088420]. Updated documentation to
suggest that the QLLR based decoders are used instead for maximum
runtime efficiency and numerical stability.
2006-08-08 Adam Piatyszek <[email protected]>
* itpp/base/array.h, tests/array_test.cpp, tests/array_test.ref:
Added new constructors and operator `=' which use string literals
for Array initialisation. There is no need to use `set_array()'
function any more. Test program improved as well. Source code of
"array.h" beautified by the way.
* tests/vec_test.cpp: Fixed improper file description.
* tests/parser_test.cpp: Fixed minor compilation problem caused by
passing C-style string as an argument of init(std::string)
function.

* itpp/base/bessel.cpp, itpp/base/bessel/jv.cpp,
itpp/base/bessel/struve.cpp, itpp/base/random.h,
itpp/protocol/tcp.cpp: Removed most of the "#pragma warning"
statements needed by MSVC++ .NET compiler (merged rev. 577:578
from itpp-3-10 branch).
* win32/itpp.vcproj: Added _CRT_SECURE_NO_DEPRECATE and
_CRT_NONSTDC_NO_DEPRECATE definitions that disable warnings on
some deprecated C standard library and POSIX-compilant functions
(merged rev. 577:578 from itpp-3-10 branch).
2006-08-04 Adam Piatyszek <[email protected]>
* itpp/base/parser.cpp, itpp/base/parser.h, tests/parser_test.cpp,

[1418707]).
2006-08-03 Adam Piatyszek <[email protected]>
* itpp/base/vec.cpp: Changed the way "a:b:c" format is parsed when
(b = 0) and (a = c). Now it returns "a". Thanks to Erik for
finding this bug (merged rev. 556:566 from a temporary sandbox
branch).
2006-08-03 Erik G. Larsson <[email protected]>
* itpp/comm/rec_syst_conv_code.h: Documentation update (fixes bug
[1532371]).
2006-07-26 Adam Piatyszek <[email protected]>
* tests/rec_syst_conv_code_test.cpp,
tests/rec_syst_conv_code_test.ref: Fixed a minor bug in the RSC
code test program. The generator polynomials were initialised with
a string using octal notation, which is not supported by Vec<>
parser yet.
* itpp/base/parser.cpp: Minor change in findname() function to
adapt the parser to recent changes in Vec and Mat classes. Now
fields in a temporary parsed string are separated with spaces
instead of commas (merged rev. 556:566 from a temporary sandbox
branch).
* tests/mat_test.cpp, tests/mat_test.ref, tests/vec_test.cpp,
tests/vec_test.ref: Added vector and matrix initialisation tests
with strings (merged rev. 556:566 from a temporary sandbox
branch).
2006-07-25 Adam Piatyszek <[email protected]>
* itpp/base/mat.cpp, itpp/base/mat.h, itpp/base/vec.cpp,
itpp/base/vec.h (merged rev. 556:566 from a temporary sandbox
branch):
New functions for initialising vectors and matrices from strings
implemented. Main features of the improved parser are as follows:
- Decimal, octal and hexadecimal notation support according to
C/C++ conventions, i.e. octal number starts with `0' (e.g. `0133',
`077'), decimal number starts with `1-9' or is a single `0' digit,
hexadecimal number starts with `0x' or `0X' prefix and has at
least one `0-9', `a-f'or `A-F' digit after (e.g. 0xFF, 0x0,
0x070). Various representations can be mixed in one string.
- Signed numbers supported, i.e. with `+', `-' or nothing in
front, e.g. `-1000', `+0133', `-0x1'
- Vector values can be separated with spaces ` ', tabs `\t' or
comma `,', e.g. " -1 22, 47 0x5, 077"
- Matlab's "a:b" or "a:b:c" notation for both increasing and
decreasing values supported, e.g. "0:2:10", "-9:-18", "4:-1:0",
"0x0:0x8:0xFF"
- Matrix rows separated with a single semicolon `;'
- Detection of syntax errors during parsing
2006-07-19 Adam Piatyszek <[email protected]>
* INSTALL: Updated to reflect recent changes in installation.doc.
* doc/local/installation.doc: Installation documentation updted
according to the recent changes in fortran compiler detection.
* configure.ac: Added explicit check for a fortran compiler. If
not found, BLAS, CBLAS and LAPACK are not checked. BTW, obsolete
AC_HELP_STRING macros replaced with AS_HELP_STRING.
2006-07-18 Adam Piatyszek <[email protected]>
