The classical Fit function does the job if you want a linear combination of functions, for example: \sum a_ij x^i y^j if you want something nonlinear, as: \sum cos( a_j x^j) exp(b_j y^j) you should use the Standard Math Package: Statistics`NonlinearFit For NonlinearFit you can find some information on an older more simpler version on MathSource.
