Concatenating column vectors using numpy arrays

Question

I\'d like to concatenate \'column\' vectors using numpy arrays but because numpy sees all arrays as row vectors by default, np.hstack and np.concatenate

Answer 1

I tried the following. Hope this is good enough for what you are doing ?

>>> np.vstack((a,b,c))
array([[ 0,  1],
       [ 2,  1],
       [-1, -1]])
>>> np.vstack((a,b,c)).T
array([[ 0,  2, -1],
       [ 1,  1, -1]])
