Hi guys,

I am looking to integrate the attached equation using C++.

I was wondering if you could tell me what type of equation it is, and if you could recommend an algorithm to use to solve this (and why)?

I need to use this for 100's of points (m,n) on a grid so a fastish algorithm would be preferred.

Please see attached equation. Your advice and help is much appreciated.

don't know about no algorithm, but solving it with a computer seems very straightforward.
 
What is i in the expression?
Is it a positive integer or the imaginary number √-1 ?
