Remarks

Use the RationalCurve class to represent a rational function that can be used in non-linear least squares fitting.

A rational curve is a quotient of two polynomials. The degree of the polynomials must be specified when the curve is constructed. A rational curve has n+d+1 parameters, where n is the degree of the polynomial in the numerator, and d is the degree of the polynomial in the denominator. The first n+1 parameters are the coefficients of the polynomial in the numerator, starting with the constant term. The remaining d parameters are the coefficients of the polynomial in the denominator, starting with the linear term. The polynomial in the denominator always has constant term 1.

For details on how to fit a curve of this type, see the NonlinearCurveFitter class.
