The 'a\b' operator works well on my old PC (i7/4core/matlab2017). It can use all 4 CPU. But on my new PC(I9 10900XE), it can only use 1 core, whatever in Matlab2015,2017 or 2019b.
OS：win10 ent
env：
NUMBER_OF_PROCESSORS=20
PROCESSOR_ARCHITECTURE=AMD64
PROCESSOR_REVISION=5507
version -blas ： Intel(R) Math Kernel Library Version 2018.0.3 Product Build 20180406 for Intel(R) 64 architecture applications, CNR branch AVX512
maxNumCompThreads : 10
I also try to install intel PS2013 and then PS2018, but it seems useless.
