Hiya, I know curve fitting has been used a lot in science related subjects. However, as far as I know, there is no mathematics software that can do ratio polynomial fit, including Mathematica. Am i right?? I have a set of datas, and I want to fit them according to the form of y = G(x)/H(x), where G(x) = a1*x^n +a2* x^(n-1)+...+I*(b1*x^m + b2*x^(m-1) ...+...) and H(x) = c1*x^n +c2* x^(n-1) + ... a,b,c are coefficeints, that iw ant to find from teh curve fitting. n and m are degree of polynomials. x is variable. Please advise. Regards Colin
