Comment(by rbeezer):
Some linear algebra results come back as Sequence objects, so maybe that's
the reason. But you are right, it doesn't seem to matter. With patch:
{{{
sage: A = matrix(QQ, 5, range(25))
sage: eigen = A.eigenvectors_right()
sage: basis = eigen[0][1]
sage: basis
[
(1, 0, 0, -4, 3),
(0, 1, 0, -3, 2),
(0, 0, 1, -2, 1)
]
sage: type(basis)
<class 'sage.structure.sequence.Sequence_generic'>
sage: U = span(basis)
sage: U
Vector space of degree 5 and dimension 3 over Rational Field
Basis matrix:
[ 1 0 0 -4 3]
[ 0 1 0 -3 2]
[ 0 0 1 -2 1]
}}}
Running tests right now.
