Right... but Scipy has all sorts of ways to do all sorts of things. I'm usually doing somewhat more complex linear algebra stuff, such as calculating eigenvectors and various sorts of decomposition, including our favorite, singular value decomposition. It's is all a bit taxing our systems, especially when I want to do really large matrices (like 50K x 10K). If it goes into virtual memory, there isn't enough time in the universe to finish some of these things. If anyone is wondering, I'm doing this sort of thing in relation to computational linguistics and so forth.
