matrix_mul(3) Allegro manual matrix_mul(3) NAME matrix_mul, matrix_mul_f - Multiplies two matrices. Allegro game pro- gramming library. SYNOPSIS #include <allegro.h> void matrix_mul(const MATRIX *m1, const MATRIX *m2, MATRIX *out); void matrix_mul_f(const MATRIX_f *m1, const MATRIX_f *m2, MATRIX_f *out); DESCRIPTION Multiplies two matrices, storing the result in out (this may be a du- plicate of one of the input matrices, but it is faster when the inputs and output are all different). The resulting matrix will have the same effect as the combination of m1 and m2, ie. when applied to a point p, (p * out) = ((p * m1) * m2). Any number of transformations can be con- catenated in this way. Note that matrix multiplication is not commuta- tive, ie. matrix_mul(m1, m2) != matrix_mul(m2, m1).
