[Numpy-discussion] I can slice but I can't assign

[Keith G. <kwg...@gm...>]

>> x = M.matrix([[1, 2], [3, 4]])
>> x
matrix([[1, 2],
        [3, 4]])

>> y = M.matrix([[5], [6]])
>> y
matrix([[5],
        [6]])

>> idx = M.where(x[:,0].A < 100)[0]
>> idx
array([0, 1])


>> x[idx,0]   # <---- This works
matrix([[1],
        [3]])

>> x[idx,0] = y    # <---- But this doesn't work. How can I make it work?

ValueError: array is not broadcastable to correct shape
