I tend to use the source code from the Numerical Recipees book. I am not
sure whether the code is public-domain---i.e. whether one would be allowed
to write and sell a commercial application incorporating the compiled version
of some of their routines---but for private applications, it is quite reliable,
written nicely in C by experts in the numerics field, available in C source
code for something like $25, and comes with a fat book explaining how each
routines work.
