When using parallel computing toolbox can I just replace all my "for" loops with "parfor" ?

I'm running an intensive calculation and want to minimise my computation time.

No, there are a lot of restrictions on what can be inside a parfor

If you have a NVIDIA graphics GPU, you can probably only get decent performance for single precision, as double precision on those is either 1/32 or 1/24 of the single precision performance until you get to relatively high end.

The 1080ti has FP64 performance of about 332, which is 1/32 of the FP32 rate; https://en.wikipedia.org/wiki/GeForce_10_series . That is not bad compared to the other graphics cards, but it is far far below the FP64 performance available in some of the Tesla series; https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units#Tesla or the Quadro GP100 (about 5300)
