With the help of matrix.sum() method, we are able to find the sum of values in a matrix by using the same method.

Syntax : matrix.sum() Return : Return sum of values in a matrix

Example #1 : In this example we are able to find the sum of values in a matrix by using matrix.sum() method. Python3 1=1

# import the important module in python
import numpy as np
           
# make matrix with numpy
gfg = np.matrix('[4, 1; 12, 3]')
           
# applying matrix.sum() method
geek = gfg.sum()
 
print(geek)

Example #2 : Python3 1==

# import the important module in python
import numpy as np
           
# make matrix with numpy
gfg = np.matrix('[4, 1, 9; 12, 3, 1; 4, 5, 6]')
           
# applying matrix.sum() method
geek = gfg.sum(axis = 1)
 
print(geek)
