The Intel IPP math functions for 2D, 3D, and 4D vectors operate on the following data objects:
2D vector,
represented by a continuous array of two float numbers.
3D vector,
represented by a continuous array of three float numbers.
4D vector,
represented by a continuous array of four float numbers.
4x4 matrix,
represented by a continuous array of 16 float numbers.
For all these objects, continuous arrays mean that stride2= sizeof(float) for the vectors and matrices, and stride1= 4*sizeof(float) for the matrices.
