With the help of Numpy matrix.nonzero()
method, we can get the index value of nonzero value from given matrix. It always gives us 2-D array.
Syntax : matrix.nonzero()
Return : Return index value of nonzero from given matrix
Example #1 :
In this example we can see that we are able to get the index value of nonzero from a given matrix with the help of method matrix.nonzero()
.
import numpy as np
gfg = np.matrix( '[64, 1; 0, 3]' )
geeks = gfg.nonzero()
print (geeks)
|
Output:
(array([0, 0, 1]), array([0, 1, 1]))
Example #2 :
import numpy as np
gfg = np.matrix( '[11, 0, 3; 34, 0, 65; 7, 68, 0]' )
geeks = gfg.nonzero()
print (geeks)
|
Output:
(array([0, 0, 1, 1, 2, 2]), array([0, 2, 0, 2, 0, 1]))
