The simplest matrix is a two-dimensional continuous array (see Figure “Regular and Irregular Matrices”, case A). In Intel IPP for small matrices, matrices are represented by more complicated structures. Any elements stored in memory can be combined into an IPP MX matrix. In IPP MX there is a difference between regular and irregular matrices. The matrix is called regular, if its row elements are equally spaced in memory and its rows are equally spaced in memory: see Figure “Regular and Irregular Matrices”, cases A, B. If one or both of these conditions is false, the matrix is called irregular: see Figure “Regular and Irregular Matrices”, cases C, D.
In this manual matrix sizes are given as width x height.
