Hiya, I was told that the add-on packages in Mathematica are useful to solve more complicated and particular problems. Thanks! I tried to use Calculus'Pade' and Statistic'Nonlinear' to solve my initial problem. i am nearly there. The problems that I have when I used 1) Caluculus'Pade' is that the input has to be a function instead of data points. 2) Statistic'Nonlinear' is that I wouldnt be able to fit complex ratio polynomial in the form of (a1*x^n + a2*x^(n-1) + ... + I * (b1*x^m + ... ) )/(c1*x^n + c2*x^(n-1)) Please advise Regards Colin
