OK, so this is my newest problem. In fact I'm trying to make an algorithm for resolution of an equation of nonlinear propagation called KZK, in Matlab I've made already the program, but the problem is that's so slow so I'm searching for programming in C, I've found an easy algorithm for the inverse of a tri-diagonal matrix it's called Thomas but I'm in need of complex numbers I'm hearding about a librarie in C can you give a link or something else for this. I'm open for other solutions, And I'm programmin under turbo C in windows.

Thanks a lot.
