Smith Form seems to be unhappy about getting a sparse matrix:
{{{
sage: B=diagonal_matrix(ZZ, [3,4])
sage: B.is_sparse()
True
sage: B.smith_form()
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
<snip>
TypeError: unable to coerce <class 'sage.rings.ideal.Ideal_pid'> to an
integer
sage: C=B.dense_matrix()
sage: C.smith_form()
(
[ 1 0] [ 1 1] [-1 -4]
[ 0 12], [-4 -3], [ 1 3]
)
}}}
