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
       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).
