Dear list members,

I've got a small question on matrix multiplications in a C code. Because 
of a really cpu demanding likelihood, I had to use a C code within an R 
function wrapper. I'm pretty sure that there is already one good code 
for matrix multiplication in C - maybe in the R source code itself - but 
I wasn't able to find it.

Anyone as an idea on how to handle matrix multiplications?

Best,
Mathieu
