So, for the first time I am trying to do multiple integration using TF3 for 3 variables. Here’s below what I wrote in my code which is showing error when compiled. It is showing that it can’t call Wrapped function. I don’t know how to do triple integration in ROOT and where is my error in this code. Any help in this regard would be highly appreciated. Thank you.
Hi,
So, I did the following way but it still didn’t work out…(P.S. “integrand_sigma” is a function defined above the main function in my code where the value of integrand_sigma is already calculated):
Error: Can’t call WrappedMultiTF1::WrappedMultiTF1(Sigma) in current scope pion_eta.C:191:
Possible candidates are…
Error: class,struct,union or type WrappedMultiTF1 not defined pion_eta.C:191:
