Dear Niklas, As I'm taking this project again, I bumped into some questions that you may answer me immediately, I'm sure!
Well I'm trying to discover which and where is the function that performs the pivoting calculation. By the hints you gave me before I'm searching for this function on dptabres.cxx, and there I found a Calculate function, but it makes me believe that it is not the function I'm searching for... Also I am searching for the input for this calculation, and that function takes some arguments that I can't assume as a structure holding all the data to perform such computation. Can you give me some more hints about the form that the input takes for the calculation? And which is the main function where the pivoting calculation starts? Thank you very much!
