Sorry, I misspoke: by native I meant to say implemented in fortran.

Here are the average times of a few operations.

operation  | msecs  (mean of 100 runs)
-----------+---------
(m.*! a b) | 1351.6
(m.+! a b) |    8.6
(m* c d)   |   15.2

A,B = 500x500 real-matrices
C = 500x1 real matrix
D = 1x500 real matrix

(Machine: 1.2GHz Athlon w/ 512M RAM running Allegro 6.0 on Debian Linux)
