I have a graph ‘gg3’ defined as TGraphErrors type. I want to get spline interpolations between all the points and also get errors for them. May I know how I do that?
For example, I did the following to get the interpolations:
TSpline3 *s3 = new TSpline3(“grSpl3”,gg3);
interpolX = s3->Eval(x);
That way I could get the value of the interpolation, but not the error on it. Would you please help me if there is a way?
If it’s not too much, may I know what’s the difference between TSpline, TSplinePoly, TSpline3 and TSplinePoly3 and so on?
