NAME

       matrix_mul, matrix_mul_f - Multiplies two matrices. Allegro game programming 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 duplicate 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 concatenated in  this  way.  Note  that  matrix  multiplication  is  not
       commutative, ie. matrix_mul(m1, m2) != matrix_mul(m2, m1).
