| Sep 22, 2015 at 9:22 | comment | added | Funzies | @MarcoB Thanks for your reply. Indeed, your code gives a good speed-up. However, to ensure convergence I need to take a lot more terms into account. Going to 100 terms, the results becomes 'weird', probably due to numerical errors as you mentioned. Is there any way this can be fixed? | |

@march I noticed that as well, while playing with the machine-precision version. I amended my answer accordingly, also including your suggestion to prevent needless recalculation of the intensity expression.
