I have been experimenting with matrix multiplication with transpose or PermutedDimsArray functions. My goal was to find the cost for multiplying a transposed array, and I encountered a behavior of transpose I cannot explain. My initial hypothesis was this: In Julia, a matrix A is stored in column-m…

Multiplication after transpose much faster than multiplication after PermutedDimsArray

Hi,

Thanks for the replies. I understand it has to do with OpenBLAS implementation.
As a related side question, is there a plan to develop a way to dispatch on array storage types in the future?
