NumPy: Compute cross-correlation of two given arrays

NumPy Statistics: Exercise-9 with Solution

Write a NumPy program to compute cross-correlation of two given arrays.

Sample Solution:-

Python Code:

import numpy as np
x = np.array([0, 1, 3])
y = np.array([2, 4, 5])
print("\nOriginal array1:")
print("\nOriginal array1:")
print("\nCross-correlation of the said arrays:\n",np.cov(x, y))

Sample Output:

Original array1:
[0 1 3]

Original array1:
[2 4 5]

Cross-correlation of the said arrays:
 [[2.33333333 2.16666667]
 [2.16666667 2.33333333]]
