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.
