Numpy: Concatenating multidimensional and unidimensional arrays

unutbu's answer works in general, but in this case there is also np.column_stack

>>> xarray([[1, 2],       [4, 5]])>>> yarray([3, 6])>>> np.column_stack((x,y))array([[1, 2, 3],       [4, 5, 6]])

python arrays numpy concatenation

Also works:

In [22]: np.append(x, y[:, np.newaxis], axis=1)Out[22]: array([[1, 2, 3],       [4, 5, 6]])
