#5460: [with patch, needs review] deprecate 'invert' in matrix_rational_dense
----------------------------+-----------------------------------------------
Reporter: jhpalmieri | Owner: jhpalmieri
Type: defect | Status: new
Priority: minor | Milestone: sage-3.4.1
Component: linear algebra | Keywords:

Comment(by rbeezer):
Replying to [ticket:5460 jhpalmieri]:
I get the deprecation warning with a singular matrix, but not with a
nonsingular matrix. Is this the desired/expected behavior? Otherwise, it
looks good, passed tests, etc.
