----------------------------+-----------------------------------------------
Reporter: cwitty | Owner: was
Type: defect | Status: new
Priority: blocker | Milestone: sage-3.3
Component: linear algebra | Keywords:
----------------------------+-----------------------------------------------
Consider:
{{{
sage: vector(ZZ, range(3)).apply_map(lambda x: x+1)
(1, 2, 3)
sage: vector(ZZ, range(3), sparse=True).apply_map(lambda x: x+1)
(0, 2, 3)
}}}
and
{{{
sage: matrix(ZZ, range(3)).apply_map(lambda x: x+1)
[1 2 3]
sage: matrix(ZZ, range(3), sparse=True).apply_map(lambda x: x+1)
[0 2 3]
}}}
