多项式曲线拟合 任意介数 Purpose - Least-squares curve fit of arbitrary order



working in C++ Builder 2007 as a template class,

using vector<FloatType> parameters.

Added a method to handle some EMathError exceptions.

If do NOT want to use this just call PolyFit2 directly.



usage: Call PolyFit by something like this.



　　　　　　 CPolyFit<double> PolyFitObj

　　　　　　 double correlation_coefficiant = PolyFitObj.PolyFit(X, Y, A)



　　　　　　 where X and Y are vectors of doubles which must have the same size and

　　　　　　 A is a vector of doubles which must be the same size as the number of

　　　　　　 coefficients required.



returns: The correlation coefficient or -1 on failure.

produces: A vector (A) which holds the coefficients.
