how to combine 2 numpy arrays code example

Example 1: numpy merge arrays

>>> a = np.array([[1, 2], [3, 4]])
>>> b = np.array([[5, 6]])
>>> np.concatenate((a, b), axis=0)
array([[1, 2],
       [3, 4],
       [5, 6]])
>>> np.concatenate((a, b.T), axis=1)
array([[1, 2, 5],
       [3, 4, 6]])

Example 2: join two numpy arrays

numpy.concatenate([arr1, arr2]) # Joining arr1 and arr2

Example 3: how to append two numpy arrays

#concatenating through column(axis = 1)
numpy.concatenate((N,M),1)
