OK , so I mtimesx suggest that to make SPEEDOMP mode to work , mtimesx should be compliled by OPENMP compiler. i.e MSVC or Intel Intel Parallel Studio XE . Free MinGW64 Compiler will complie mtimesx but does not support OPENMP.
I have installed MSVC 2019 . But still strugling to get it setup for matlab as matlab is not detecting the complier when using
mex -setup CPP -v ;
Below link discussed without conclusion.
But even I acheive and get OPENMP complier will I get speed improvement by using SPEEDOMP over SPEED mode ?
best.
