Rational Polynomial curve fitting

Fits a function to a quotient of polynomials

You are now following this Submission

This program finds 2 polynomials, Num(x) and Den(x) such that Num(xi)/Den(xi) = y(xi) in a least squares sense.

The function, y(xi), may have infinite values and zero values.

This is an upgrade to Matlab's Polyfit command.
