With the help of Numpy matrix.diagonal() method, we are able to find a diagonal element from a given matrix and gives output as one dimensional matrix.
Syntax :
matrix.diagonal()Return : Return diagonal element of a matrix
Example #1 :
In this example we can see that with the help of matrix.diagonal() method we are able to find the elements in a diagonal of a matrix.
# import the important module in pythonimport numpy as np         # make matrix with numpygfg = np.matrix('[6, 2; 3, 4]')         # applying matrix.diagonal() methodLazyroar = gfg.diagonal()   print(Lazyroar) |
Output:
[[6 4]]
Example #2 :
# import the important module in pythonimport numpy as np         # make a matrix with numpygfg = np.matrix('[1, 2, 3; 4, 5, 6; 7, 8, 9]')         # applying matrix.diagonal() methodLazyroar = gfg.diagonal()   print(Lazyroar) |
Output:
[[1 5 9]]
