Recipe Objective

Have you tried to add a constant element in a matrix?

So this is the recipe on how we can add a constant to each element of a matrix.

Step 1 - Importing Library

import numpy as np

We have only imported numpy which is needed.

Step 2 - Creating Matrix

We have created a matrix a matirx on which we will perform operation. matrixA = np.array([[2, 3, 23], [5, 6, 25], [8, 9, 28]])

Step 3 - Adding an element

We have made a lambda function to add 100 in every value of matrix. We have created an object to add 100 in the vector form of matrix. add_100 = lambda i: i + 100 vectorized_add_100 = np.vectorize(add_100) print(vectorized_add_100(matrixA)) So the output comes as

[[102 103 123] [105 106 125] [108 109 128]]
