NumPy: Universal Functions Exercise-16 with Solution

In-place ufunc Operations:

Write a NumPy program that uses np.add with the out parameter to perform in-place addition on a NumPy array.

Sample Solution:

Python Code:

import numpy as np

# Create a NumPy array
array_x = np.array([1, 2, 3, 4, 5])

# Create another array to add
array_y = np.array([10, 20, 30, 40, 50])

# Perform in-place addition using np.add with the out parameter
np.add(array_x, array_y, out=array_x)

# Print the resulting array
print("Resulting Array after In-Place Addition:")
print(array_x)

Output:

Resulting Array after In-Place Addition:
[11 22 33 44 55]

Explanation:

• Import NumPy Library:
• Import the NumPy library to handle array operations.
• Create NumPy Arrays:
• Define two NumPy arrays 'array_x' and 'array_y' with example data.
• Perform In-Place Addition:
• Use np.add() with the out parameter to add 'array_y' to 'array_x' in-place, storing the result directly in 'array_x'.
• Finally print the resulting array to verify the in-place addition.
