Yea...I can write reasonably performant Fortran, but have no clue how to do matrices in C without resorting to the numerical methods book that doesn't allow you to use it's algorithms and has the dumbest license ever (is it called numerical recipes in C)...the Amazon comments are illuminating.

We commonly used the GSL library.

That might work for siof my use cases, but it stinks that you can't use it for a commercial product.

GSL has its own set of license 'problems' to be aware of in that it's GPL and not LGPL.
