Consider the following arrays: a = np.array([0,1])[:,None] b = np.array([1,2,3]) print(a) array([[0], [1]]) print(b) b = np.array([1,2,3]) Is there a simple way to concatenate these two arrays in a way that the latter is broadcast, in order to obtain the following? array([[0, 1, 2, 3], [1, 1, 2, 3]]) I've seen there is this closed issue with a related question. An alternative is proposed involving np.broadcast_arrays, however I cannot manage to adapt it to my example. Is there some way to do this, excluding the np.tile/np.concatenate solution?
