#12370: Change is_singular to use rank instead of determinant
------------------------------+---------------------------------------------
Reporter: jlopez | Owner: jason, was
Type: enhancement | Status: new
Priority: major | Milestone: sage-5.0
Component: linear algebra | Keywords: matrices, is_singular
Work_issues: | Upstream: N/A

------------------------------+---------------------------------------------
The matrix method is_singular for matrices currently returns
{{{
self.det() == 0
}}}
It would be faster to check for full rank instead.
