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 python import numpy as np
# make matrix with numpy gfg = np.matrix( '[6, 2; 3, 4]' )
# applying matrix.diagonal() method geeks = gfg.diagonal()
print (geeks)
|
Output:
[[6 4]]
Example #2 :
# import the important module in python import numpy as np
# make a matrix with numpy gfg = np.matrix( '[1, 2, 3; 4, 5, 6; 7, 8, 9]' )
# applying matrix.diagonal() method geeks = gfg.diagonal()
print (geeks)
|
Output:
[[1 5 9]]
