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]]
