| Apr 20, 2023 at 13:26 | comment | added | John Taylor | @LukasLang : the toy task I implemented here captures some of the general features of the realistic task I am dealing with, so I expect that I would be able to adapt any algorithm optimizations to the realistic task. "One thing that appears to give a factor of 2" - such speedup is also very crucial for me. | |

What makes you think this can be improved? The computation contains only simple functions, so unless you go into extreme C-level optimizations (at which point you should probably just write C code), you'll need some algorithm-level optimizations (which at some point depends on the exact problem at hand and might not be solvable using only a toy problem). One thing that appears to give a factor of 2 at least is to compute Sin[phrange] and MapAt[Cos,thzrange,{All,1}], and pass that in instead of computing Sin[ph] and Cos[th] every time.

| Apr 19, 2023 at 11:31 | comment | added | John Taylor | @AlexTrounev : it may be expressed in terms of some function of x1, x2. | |
