Maybe an obvious question, but first time I’ve tried this in core.matrix
and I’m finding it a bit tough to locate what I’m looking for. Is there a way to do the equivalent of [index arrays](http://docs.scipy.org/doc/numpy-1.10.1/user/basics.indexing.html#index-arrays) in numpy?
>>> mat
array([[1, 2, 3],
[4, 5, 6],
[7, 8, 9]])
>>> mat[[2,1,0]]
array([[7, 8, 9],
[4, 5, 6],
[1, 2, 3]])
>>> mat[[1,1,1,1,1]]
array([[4, 5, 6],
[4, 5, 6],
[4, 5, 6],
[4, 5, 6],
[4, 5, 6]])
