Mathematica has nice curve fitting routines(Fit, NonlinearFit) and it has a decent(as long as symbolic derivatives are available for the basis functions) minimization routine for least squares fitting(FindMinimum) and it has good DE solvers(DSolve, NDSolve). In addition, mathematica is a very powerful high level programming language even without all the built-in numerical routines, so you can write anything you need anyway.
