I would like to ask a question about how to use userdata argument in cuba subroutines Please tell me if you can help me in this problem Thank you for your cooperation

Just access the global variable from the function.

JohannesBuchner commented 4 years ago

Alternatively, you can also use a class method as a callback function, and access self.

I have passed two parameter a(i),b(i) for i=1,n to function integrand via /common/ . I call in a cicle cuhre subroutine . For each a(i),b(i), cuhre subroutine computes very well integrand. I want to write a(i),b(i) and "integral" (in a file). Now cuhre does not write the results in the manner wanted by me ( It write more n lines ). Please excuse my english. I hope you understand what i want to say

If you need help with cuba, please ask the author (Thomas Hahn). I only added a python interface (part of the pymultinest package).
