ndarray

This is a simple single header implementation of n-dimensional array in C++11 standard. The storage layout is column major (same as Fortran/Matlab). Current implementation only supports limited features. More features will be added in the future, ie. iterator.

Installation

Simply include the header in your source file to use.

Documentation

Many member functions of ndarray accept variable length argument. Safe and efficient variable length argument is implemented using initializer_list.

To use debug features such as boundary check, add #define _DEBUG at the beginning of header or use compiler flag -D_DEBUG.

Some major usage of ndarray are listed below:

1. Declare array

   ndarray <double> a(); //declare empty array
   ndarray <double> a({2,2,2}); //declare an ndarray using inializer_list with number of element in each dimension

2. Use setup to create a new array

   a.Setup({0,0,1});

3. Initialize array elements to value

   a=5.;

4. Access/set array element

   a({0,0,1}); //access/set using initializer_list
   a(1); //access/set as if the array is 1D array

5. Get pointer of array element

   a.GetData({0,0,1}); //get pointer using initializer_list
   a.GetData(1); //get pointer as if the array is 1D array

6. Reshape array

   a.Reshape({1,4,2}); //reshape using initializer_list
