Comment(by gbe):
The current version is working correctly and is probably usable in most
applications. That said, I'm leaving the status as needs works as there
are a few more (mostly minor, I think) remaining things to do:
Remaining issues:
* Fix the doctests in matrix2.pyx and matrix_callable_symbolic_dense.pyx.
I know v2 is has these two files failing doctests; it may be that other
files are also failing as I have not yet run sage --testall.
* Partial evaluation does not return a callable matrix. See #12302 for
more details, as this is the exact same issue and the fix should be
(basically) the same - a modification to _ _call_ _() so the function
recognizes partial evaluation.
Comments:
* I'm leaving the definition of function() in matrix2.pyx unless someone
with more experience withh the matrix module chimes in and says
differently.
* While working with this bug I unearthed bug #12302. In addition to the
fixes probably being nearly identical, 12302 may have implications for
this patch since
