I'm working on a Mathematica code that involves nested NIntegrate and NSum with oscillatory integrands, but I'm encountering several non-numeric evaluation errors. The relevant part of the code is below:
When I run this, I get errors like:
Power::infy: Infinite expression 1/0 encountered.
NIntegrate::inumr: The integrand has evaluated to non-numerical values for all sampling points.
NSum::nsnum: Summand is not numerical at point m = 100.
