Hi, I'm observing the following with version 9.1 (but not with 9.0 where the behavior is correct):
sage: m = matrix(SR, [0]) sage: b = vector([1]) sage: m.solve_right(b) (0) This should of course raise ValueError: matrix equation has no solutions It seems to be specific to inexact coefficients (the same problem occurs for RR and CC, but not for QQ).
