Right the dimensions I gave were wrong. What do I need to do for m>=n (more rows than columns)? Can I use the same function?
When I run the script written by Nils (thanks!) I get: from numpy.random import rand, seed ImportError: No module named random But importing numpy works ok. What do I need to install? Thanks again!
