#4972: matrix setitem should deal with slicing
----------------------------+-----------------------------------------------
Reporter: jason | Owner: was
Type: defect | Status: new
Priority: major | Milestone: sage-3.3
Component: linear algebra | Keywords:
----------------------------+-----------------------------------------------
The following should work:
{{{
a=matrix(QQ,3,[1,3,4,3,2,3,6,4,5])
a[1,:]=a[0,:]
}}}
Instead, I get an error:
{{{
