[numpy] stack 결과

1) np.vstack & np.stack

t = [[1, 2, 3], [4, 5, 6]]

np.vstack(t)
>> array([[1, 2, 3],
          [4, 5, 6]])
          
np.stack(t, axis=0)
>> array([[1, 2, 3],
          [4, 5, 6]])

 

 

2) np.hstack & np.stack

t = [[1, 2, 3], [4, 5, 6]]

np.hstack(t)
>> array([1, 2, 3, 4, 5, 6])
          
          
np.stack(t, axis=1)
>> array([[1, 4],
          [2, 5],
          [3, 6]])
