Python | Numpy matrix.ptp()

With the help of Numpy matrix.ptp() method, we can get the peek-to-peek value that is (maximum-minimum) along the axis from given matrix.

Syntax : matrix.ptp(axis)

Return : Return peek-to-peek value from given matrix

Example #1 :
In this example we can see that we are able to get the peek-to-peek value from a given matrix with the help of method matrix.ptp().

# import the important module in python
import numpy as np

# make matrix with numpy
gfg = np.matrix('[64, 1; 12, 3]')

# applying matrix.ptp() method
geeks = gfg.ptp(1)

print(geeks)

Output:

[[63]
 [ 9]]

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.ptp() method
geeks = gfg.ptp(0)

print(geeks)

Output:

[[ 6  6 15]]
