Python Programming illustrating

numpy.empty method

import numpy as geek

b = geek.empty(2, dtype = int) print("Matrix b : \n", b)

a = geek.empty([2, 2], dtype = int) print("\nMatrix a : \n", a)

c = geek.empty([3, 3]) print("\nMatrix c : \n", c)

`

Output :

Matrix b : [ 0 1079574528]

Matrix a : [[0 0] [0 0]]

Matrix a : [[ 0. 0. 0.] [ 0. 0. 0.] [ 0. 0. 0.]]

Note : empty, unlike zeros, does not set the array values to zero, and may therefore be marginally faster. Also, these codes won’t run on online-ID. Please run them on your systems to explore the working
