Is there a way to access multiple elements of a matrix in a way that is similar to Matlab? I have a list of indices for one matrix that I want to copy into another matrix using another list of indices. It's a nonlinear mapping so I haven't found an easy way to do this other than in Matlab. I've tried going through the list and copy each item using At, but that is much too slow. Any other options to try?
Thx
