NumPy: Normalize a 3x3 random matrix

NumPy: Random Exercise-7 with Solution

Write a NumPy program to normalize a 3x3 random matrix.

Sample Solution:

Python Code :

import numpy as np
x= np.random.random((3,3))
print("Original Array:")
print(x)
xmax, xmin = x.max(), x.min()
x = (x - xmin)/(xmax - xmin)
print("After normalization:")
print(x)

Sample Output:

Original Array:                                                        
[[ 0.89372503  0.99865458  0.77120044]                                 
 [ 0.67632984  0.99990084  0.64110391]                                 
 [ 0.34845794  0.66557903  0.29031742]]                                
After normalization:                                                   
[[ 0.85036881  0.99824367  0.67769765]                                 
 [ 0.54399864  1.          0.49435553]                                 
 [ 0.08193614  0.52884777  0.        ]]

Python: Tips of the Day

Clamps num within the inclusive range specified by the boundary values x and y:

Example:

def tips_clamp_num(num,x,y):
  return max(min(num, max(x, y)), min(x, y))
print(tips_clamp_num(2, 4, 6))
print(tips_clamp_num(1, -1, -6))

Output:

4
-1
