Comment (by SimonKing):
With the new commits, there is full doctest coverage for the !MeatAxe
wrapper. Both
{{{
sage -t --optional=sage,meataxe src/sage/matrix/matrix_gfpn_dense.pyx
}}}
and
{{{
sage -t src/sage/matrix/matrix_gfpn_dense.pyx
}}}
pass.
Moreover, as I have announced above, I can now handle errors in !MeatAxe.
Another change: I have removed the `__pow__` method: The default `__pow__`
method automatically uses Strassen multiplication and is thus faster than
the previous method, which called !MeatAxe's `MatPower` (which doesn't use
Strassen).
Probably I have to work on several doctests in other files: All tests
depending on a random matrix may fail with meataxe, thus, for these cases
I need to force usage of `Matrix_generic_dense`.
