Good to know.

Regularly invertible matrices (for instance of finite size); and I think, that even infinite matrices can be included, if they are triangular (row- or column-finite) or, if not triangular, at least if some other condition holds (on their eigenvalues or the like). I'll have to perform some more tests...
