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?
