* summary: [with patch, positive review] matrix exponential for general
matrices => [with patch, needs work] matrix
exponential for general matrices
Comment:
This patch does not compile for me:
{{{
python2.5 `which cython` --embed-positions --incref-local-binop
-I/scratch/mabshoff/release-cycle/sage-3.2.2.alpha2/devel/sage-main
-o sage/matrix/matrix_mod2_dense.c sage/matrix/matrix_mod2_dense.pyx
Error converting Pyrex file to C:
------------------------------------------------------------
...
a = t.transpose()
right_mat = right_mat* s.transpose()
return left_mat, a, right_mat
def exp(self):
^
------------------------------------------------------------
/scratch/mabshoff/release-cycle/sage-3.2.2.alpha2/devel/sage-main/
sage/matrix/matrix2.pyx:4914:4: def statement not allowed here
Parallel build failed with status 256.
sage: There was an error installing modified sage library code.
}}}
Note that it applied with huge, i.e. 337 line, offset. This patch probably
needs a rebase.
Cheers,
Michael
