Re: 2d fit problem

 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.
