How can I perform matrix operations using NumPy?

How can I perform matrix operations using NumPy?

You can use NumPy's array functions to create matrices and perform operations like addition, multiplication, and inversion.

Can you show me how to add two matrices?

Sure! You can use the np.add() function or the + operator. For example:

import numpy as np
A = np.array([[1, 2], [3, 4]])
B = np.array([[5, 6], [7, 8]])
C = A + B
print(C)

What about multiplying matrices?

For matrix multiplication, use the np.dot() function or the @ operator. Here's an example:

C = np.dot(A, B)
# or
C = A @ B
print(C)

How do I calculate the inverse of a matrix?

You can calculate the inverse using np.linalg.inv(). For example:

A_inv = np.linalg.inv(A)
print(A_inv)
