Multiplication of two Matrices in Single line using Numpy in Python

Matrix multiplication can be succinctly performed in NumPy using just a single line of code. Let's dive right in.

Multiplication of Two Matrices in a Single Line Using NumPy

Setup:

Ensure you have NumPy installed:

pip install numpy

Single Line Matrix Multiplication:

Now, let's say you have two matrices A and B that you want to multiply.

import numpy as np

A = np.array([[1, 2], [3, 4]])
B = np.array([[2, 0], [1, 3]])

result = np.dot(A, B)
print(result)

In the example above, the function np.dot(A, B) multiplies matrices A and B. The result is printed, which, in this case, will be:

[[4  6]
 [10 12]]

However, if you want to keep the multiplication operation even more concise and intuitive, you can use the @ operator:

result = A @ B
print(result)

This also gives:

[[4  6]
 [10 12]]

Conclusion:

Using NumPy, matrix multiplication can be accomplished in a single line, making the process streamlined and efficient. Remember, for the multiplication to be valid, the number of columns in the first matrix should equal the number of rows in the second matrix.
