With the help of matrix.std() method, we are able to find the standard deviation a matrix by using the same method.

Syntax : matrix.std()
Return : Return standard deviation of a matrix

Example #1 :
In this example we are able to find the standard deviation of a matrix by using matrix.std() method.

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

Output:

4.18330013267

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.std() method 
geek = gfg.std() 
   
print(geek)
