[Matlisp-users] m.*! not native?

[Jefferson P. <jp...@cs...>]

Hi,

I was profiling some of my code yesterday, and noticed that a single m.*!
call was taking more than 90% of the run time for my program.  After
poking around a little in mtimes.lisp, it seems that m.*! isn't native.
Is this true?

I don't know BLAS very well.  Is there no way to do element-wise
multiplication in BLAS?  The non-native routine is a couple of orders of
magnitude slower than native routines of the same complexity: (e.g. m.+!
or outer-product of vectors).

If BLAS can't do this, it seems like it would be an easy Fortran routine
to write.  I could do it, though I'm not familiar with how to do foreign
functions in Allegro or cmucl.
