<b>RAND_TEST</b> is a simple example which demonstrates the use
of the rand() function to generate uniform random numbers, and to
set the seed.
<ul>
<li>
<a href = "rand_test.m">rand_test.m</a>,
the program.
</li>
<li>
<a href = "rand_test_output.txt">rand_test_output.txt</a>,
the output file.
</li>
</ul>
</p>
<p>
<b>RANDI_TEST</b> is a simple example which demonstrates the use
of the randi() function to generate random integers, and to
set the seed. The Mathworks suggests using randi() instead of randint().
<ul>
<li>
<a href = "randi_test.m">randi_test.m</a>,
the program.
</li>
<li>
<a href = "randi_test_output.txt">randi_test_output.txt</a>,
the output file.
</li>
</ul>
</p>
<p>
<b>RANDINT_TEST</b> is a simple example which demonstrates the use
of the randint() function to generate random integers, and to
set the seed. The randint() function is scheduled to be removed
from MATLAB soon.
<ul>
<li>
<a href = "randint_test.m">randint_test.m</a>,
the program.

<p>
<b>RANDN_TEST</b> is a simple example which demonstrates the use
of the randn() function to generate normal random numbers, and to
set the seed.

</p>
<p>
<b>RNG_TEST</b> demonstrates how the new RNG() function is used to
initialize and manipulate the state of the RAND, RANDINT, and RANDN random number
generators.
<ul>
<li>
<a href = "rng_test.m">rng_test.m</a>,
the program.
