python vstack numpy code example

Example 1: np vstack

>>> a = np.array([1, 2, 3])
>>> b = np.array([2, 3, 4])
>>> np.vstack((a,b))
array([[1, 2, 3],
       [2, 3, 4]])
       
>>> a = np.array([[1], [2], [3]])
>>> b = np.array([[2], [3], [4]])
>>> np.vstack((a,b))
array([[1],
       [2],
       [3],
       [2],
       [3],
       [4]])

Example 2: np.vstack python

import numpy as np
a = np.array([1, 2, 3])
b = np.array([2, 3, 4])
np.vstack((a,b))
