numpy zero matrix code example

Example 1: declare numpy zeros matrix python

import numpy as np
dimensions = (3, 3)
np.zeros(dimensions) # 3x3 zeros matrix

Example 2: np.zeros

>>> np.zeros((2, 1))
array([[ 0.],
       [ 0.]])

Example 3: np.zeros((3,3))

>>> s = (3,3)
>>> np.zeros(s)
array([[ 0.,  0.],
       [ 0.,  0.]])

Example 4: np.zeros([8,8,3])

>>> np.zeros([8,8,3])

array([[ 0.],
       [ 0.]])
