Python | Numpy matrix.sum()

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 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)

Output:

20

Example #2 :

# 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)

Output:

[[14]
 [16]
 [15]]
