Duplicate entries in a matrix

[Chris Lasher]

Now that's definitely what I'm looking for! Thanks!

By the way, was this line

In [5]: C = repeat(B, [1,2,1], axis=-1)

supposed to have a positive 1 value for axis? It works either way, I
see. Is it like a lookup, where an index of -1 returns the last value?
If that were true, I supposed the evaluation would be 1, and thus gives
the same result.

Thanks again, very much. You guys are super-helpful!
