With the help of Numpy matrix.var() method, we can find the variance of a matrix by using the matrix.var() method.
Syntax :
matrix.var()
Return : Return variance of a matrix
Example #1 :
In this example we can see that by using matrix.var() method we are able to find the variance of a given matrix.
# import the important module in python import numpy as np               # make matrix with numpy gfg = np.matrix('[4, 1; 12, 3]')               # applying matrix.var() method geek = gfg.var()     print(geek) |
Output:
17.5
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.var() method geek = gfg.var()     print(geek) |
Output:
11.5555555556
