Hi Thomas, I am not sure to understand what you mean by sampling points. Do you mean an alternative to the arrays x[12] and w[12] ? Could you provide a piece of code with some example implementation showing the speed advantage compared to the current function? If your function performs better, we can easily add a new TF1::Integral with a new prototype.
