With the help of numpy.fill_diagonal() method, we can get filled the diagonals of numpy array with the value passed as the parameter in numpy.fill_diagonal() method.
Syntax :
numpy.fill_diagonal(array, value)
Return : Return the filled value in the diagonal of an array.
Example #1 :
In this example we can see that by using numpy.fill_diagonal() method, we are able to get the diagonals filled with the values passed as parameter.
# import numpy import numpy as np # using numpy.fill_diagonal() method array = np.array([[1, 2], [2, 1]]) np.fill_diagonal(array, 5) print(array) |
Output :
[[5 2]
[2 5]]
Example #2 :
# import numpy import numpy as np # using numpy.fill_diagonal() method array = np.zeros((3, 3), int) np.fill_diagonal(array, 1) print(array) |
Output :
[[1 0 0]
[0 1 0]
[0 0 1]]
