How do you Add to a Matrix in Python?

A matrix can only be added to or subtracted from another matrix if the two matrices have the same dimensions.

Suppose we have two matrices E and D.

Example 1:

E = [[1,2],[3,4]]

DY = [[4,5],[6,7]]

then we get

E+D = [[5,7],[9,11]]

Example 2:

E = [[1,2],[3,4],[8,3]]

D = [[4,5],[6,7],[4,7]]

then we get

E+D = [[5,7],[9,11],[12,10]]

Look at the example given below to understand how to add the elements in Python:

Source Code:

Copy Code

                    
import numpy as np

  # The first matrix will be

P = np.array([[1, 2], [3, 4]])

#The second matrix will be

Q = np.array([[4, 5], [6, 7]])

print("Elements of the first matrix")

print(P)

print("Elements of the second matrix")

print(Q)

  # adding two matrix

print("The sum of the two matrices is")

print(np.add(P, Q))

Output:

Elements of the first matrix

[[1 2]

 [3 4]]

Elements of the second matrix

[[4 5]

 [6 7]]

The sum of the two matrices is

[[ 5 7]

 [ 9 11]]
