So I hit memory problems as soon as I do this for big matrices (thousands by thousands), maybe I should have mentioned that before.
So, does anyone have a less memory intensive version?

I am generally working with sparse matrices, so I think I have to kick my brain into gear enough to work out how to use the find command in this context. But any pointers would be much appreciated!

thanks
