Optimization

IPP MX functions are optimized for operations on small matrices and small vectors, particularly for matrices of size 3x3, 4x4, 5x5, 6x6, and for vectors of length 3, 4, 5, 6.

Note that when operating on small arrays, for example, a matrix array made up of two or three matrices of size 3x3, overhead caused by function call and input parameters' check may be greater than the optimization gain.
