#2136: add doctest for matrix visualize_structure
---------------------+------------------------------------------------------
Reporter: rlm | Owner: mabshoff
Type: defect | Status: new
Priority: major | Milestone: sage-3.2.2
Component: doctest | Resolution:
Keywords: |
---------------------+------------------------------------------------------
Changes (by mabshoff):
* owner: was => mabshoff
* component: linear algebra => doctest
* summary: matrix visualize_structure is completely broken on osx (at
least 10.5) -- why no doctest to catch this!?
=> add doctest for matrix visualize_structure
Comment:
This has worked for a while:

So let's add a doctest and get this ticket closed unless there already is
such a doctest. (which I believe there is).
malb?
