It's a bit of numerical computing lore that inv is bad – both for performance and for numerical accuracy. It turns out it may not be so bad <http://arxiv.org/pdf/1201.6035v1.pdf> after all, but everyone is still kind of wary of it and there are often better ways to solve problems where inv would be the naive way to do it.
