NumPy: Generate a matrix product of two arrays

NumPy Mathematics: Exercise-15 with Solution

Write a NumPy program to generate a matrix product of two arrays.

Sample Solution:-

Python Code:

import numpy as np
x = [[1, 0], [1, 1]]
y = [[3, 1], [2, 2]]
print("Matrices and vectors.")
print("x:")
print(x)
print("y:")
print(y)
print("Matrix product of above two arrays:")
print(np.matmul(x, y))

Sample Output:

Matrices and vectors.                                                  
x:                                                                     
[[1, 0], [1, 1]]                                                       
y:                                                                     
[[3, 1], [2, 2]]                                                       
Matrix product of above two arrays:                                    
[[3 1]

Python: Tips of the Day

Getting rid of unwanted characters:

You can get rid of whitespaces or any specific character using strip methods in Python. You can use either plain strip for both sides, lstrip for the left side and rstrip for the right side only.

str="+++Welcome python+++"
str.strip()

print(str)

Output:

+++Welcome python+++
