matrix_mul(3)                   Allegro manual                   matrix_mul(3)



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).
