Hi,
I have some questions on
TF1:Integral(Double_t* a, Double_t* b, Double_t* params, Double_t* epsilon).
I don't understand what is this params all about. Actually I want to
know where do you specify the integration variable.
To be more specific, I define a function fitf(double* x, double* par) and
I define TF1 f1("ff", "fitf", 0.50, 1.50) and inside the fitf function I
have a variable y, which is the one I want to be my integration variable
and not x. So, I think, y should also be an argument of the function, is
it necessary like that? or can I specify y to be my integration variable
when I call the integral routine.
And also I have been trying to use f1.DrawIntegral() and its giving
some linking errors, what am I supposed to do.
Can you give an example of some sort and explain it to me.
Thank you,
Siva.
