Subject: faster ind2sub in 3D

Hi,

This question is about speeding up ind2sub, which from a search shows me that others have also been keen to find a faster alternative. I have found some suggestions for 2D such as :

r = rem(idx-1,nrows)+1;
c = (idx-r)/nrows + 1;

but none for 3D. Can anyone show me the modifications to make for 3D pls? Thanks!
