An example of what I am doing:

Here m is an fmatrix, and v is an ivector

out = T.repeat(m, v, axis=0)

The forward pass works fine, but there is no gradient code implemented.  

This works fine when both inputs are vectors but not as above.

I am not familiar with theano enough to fill in the missing code in grad() 
for class RepeatOp().  Does anyone have suggestions as to a workaround?  I 
have not found anything even remotely helpful so far.
I've tried using tile with scan, but to no end.

Thanks.
