How to accelerate the permute for the matrix 512x512x200 by using version R2020b?
such as
A=randi(512,[512 512 200]);
B=permute(A,[3,2,1]);

The better question is what are you doing with this result downstream in your code, and is there a way to accomplish what you want to do without permuting the data (which involves deep data copies).

You can't. permute works efficiently already.
