Math-Libraries?

Hey!

I`m thinking about using C++ for a mathematical simulation of a research-problem. For this it would be very helpful to have a library containing algorithms capable for solving equation-systems by hand. Does anyone know about a library which contains such functions like "solve(equations)". Or can anyone provide me a code for solving numerical equation-systems?

hmm, a little general...

Look in math.h first, here is a a list of all the maths functions it provides

look on google or maths and equations libraries, most can be downloaded for free.
