Weird resizing issue with element_prod

[mortonjt]

I've noticed unexpected resizing when I'm doing element wise multiplication When I run the following code

import pyviennacl as pv
import numpy as np
a = pv.Matrix(np.array([ [1,2,3], [4,5,6] ], dtype=np.float32))
a.element_prod(a)

This is the output

array([[  1.,   4.,   9.],
       [ 16.,  25.,  36.],
       [  0.,   0.,   0.]], dtype=float32)

The workaround I'm going to use for now is to subset the result matrix. However, from previous experience, I know that this subsetting operation is costly

Note: I am running into this issue with the pip installable version. Has this been fixed in a more recent update? If not, is there are preferred work around solution?

Ah, yes, that does look like a bug. I'll make sure it is fixed in the git repo.

I have been saying this for a while, but I really do intend to get a new release out soon. I've had to do a lot of travelling over the last few weeks, but once I settle down again, the new release is my top priority (after my day job..).

As for an easy workaround, I will try and think of one at the same time as investigating the status of this in git master in the next couple of days.

Hey, same issue. Any updates on this? I'm using the pip install version.

@tsmithe Any chance you can have a look at this? It's probably easy for you to fix. ;-)
