Python | Numpy matrix.ptp ()

Using the Numpy matrix.ptp () method, we can get a peek-to-peek value that is (maximum- minimum) along the axis from this matrix.

Syntax: matrix.ptp(axis)

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

Example # 1:
In this example, we see that we can get the peek-to-peek value from a given matrix using the matrix.ptp () method.

# import important module in python

import numpy as np

 
# make a matrix with NumPy

gfg = np.matrix ( '[64, 1; 12, 3] ' )

  
# using the matrix.ptp () method

geeks = gfg.ptp ( 1 )

 

print (geeks)

Exit:

 [[63] [9]] 

Example # 2:

# import important module into python

import numpy as np

 
# make a matrix with NumPy

gfg = < code class = "plain"> np.matrix ( '[1, 2, 3; 4, 5, 6; 7, 8, -9] ' )

  
# using the matrix.ptp () method

geeks = gfg.ptp ( 0 )

 

print (geeks)

Exit:

 [[6 6 15]]
