FitCurveFunc(Double, Double, FuncDouble, Double, Double, Double, Double, Double, Double, Double, Double, Double, Double, Double, Double, Int32) Method

Non-linear least-squares fitting the points (x,y) to an arbitrary function y : x -> f(p0, p1, p2, p3, p4, x), returning a function y' for the best fitting curve.
