Thanks for the clarification!
((I did a quick google on Accelerate.framework before which lead me to
If you're really paranoid about speed then you might want to look at
ATLAS <http://math-atlas.sourceforge.net/>. I'm not sure what the state
of play is nowadays, but there was a point when it produced a faster
BLAS implementation than the one in Apple's Accelerate framework.
