Detailed Description

This module contains the glue code for strided matrix addition. The kernel codes (kernels) are in the Module strided matrix addition Kernels.

The Matrx Addition adds two matrices, element wise. Both matrices, and the output matrix have dimension MxN.

`pDst[m, n] = pSrcA[m, n] + pSrcB[m, n]`

There are functions for integer 32- 16- and 8-bit data types, as well as for floating-point. These functions can also be used for fix-point matrices, if they have their fix-point at the same location. The outpt matrix will then also have the fix-point at the same location.

The naming scheme of the functions follows the following pattern (for example plp_mat_add_stride_i32):

`plp_<function name>_<data type><precision>[_parallel]`

name	description
function_name	mat_add_stride
data type	{f, i, q} respectively for floats, integers, fixed points
precision	{32, 16, 8} bits

The strideX argument tells how many elements are in between the start of each row of the matrix. In other words, it is the width of the original matrix. Strided Matrix operations
