Python | Numpy matrix.sum() (original) (raw)

Last Updated : 20 May, 2019

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.

import numpy as np

gfg = np.matrix( '[4, 1; 12, 3]' )

geek = gfg. sum ()

print (geek)

Example #2 :

import numpy as np

gfg = np.matrix( '[4, 1, 9; 12, 3, 1; 4, 5, 6]' )

geek = gfg. sum (axis = 1 )

print (geek)
