Python | Numpy matrix.trace()
  • Difficulty Level : Basic
  • Last Updated : 29 May, 2019

With the help of Numpy matrix.trace() method, we can find the sum of all the elements of diagonal of a matrix by using the matrix.trace() method.

Syntax : matrix.trace()
Return : Return sum of a diagonal elements of a matrix

Example #1 :
In this example we can see that by using matrix.trace() method can help us to find the sum of all the elements of a diagonal of 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.trace() method
geek = gfg.trace()
    
print(geek)
Output:
[[7]]

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.trace() method
geek = gfg.trace()
    
print(geek)
Output:
[[13]]
