It's worth noting that matp_t is a pointer to a mat_t, which is a 1-dimensional array of 16 doubles. So whatever is done for vect_t and/or point_t (both 1-dimesional array of 4 doubles) should work similarly with the size adjusted to 16 elements. The only c type difference is that matp_t is technically just a pointer to a fastf_t (i.e., a double) and we assume there are at least 16 fastf_t values there that comprise a matrix. Cheers!
