I agree those things are a problem. I think I know why it was done: Transposition of a matrix is often written as M^T . It's difficult to support that syntax, so using M.T seems like a nice approximation. Once you have that, doing the same for conjugate and conjugate-transpose is a small step. And now that we have all these properties for order-two matrix operations, it's only natural to introduce one for inverses too. Given the ubiquity of tab-completion I agree that this is now probably a bad idea. I don't know if it's bad enough to break existing code, though. Perhaps deprecate their use? Even that has a cost. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
