#490: problem with simple matrix addition
-------------------------+--------------------------------------------------
Reporter: gauthampdas | Owner: somebody
Type: defect | Status: new
Priority: highest | Milestone: 1.0.2 Release
Component: numpy.core | Version: 1.0.1
Severity: major | Keywords:
-------------------------+--------------------------------------------------
when we declare an row vector as a matrix, and doing addition i noticed a
problem.
{{{
>>> a=mat([1,2,3])
>>> a+transpose(a)
matrix([[2, 3, 4],
[3, 4, 5],
[4, 5, 6]])
>>> a+a
matrix([[2, 4, 6]])
}}}
In my application i have to handle different matrices and vectors. Just
noticed it. This is a simple mistake but can make big errors
