Question
How do you perform matrix multiplication on the numpy arrays A and B ?
1 point
np.dot(A,B)
A*B
A+B
Solution
To perform matrix multiplication on numpy arrays A and B, you can use the np.dot(A, B)
function. Here are the steps:
- Import the numpy library:
import numpy as np
- Define your numpy arrays. For example:
A = np.array([[1, 2], [3, 4]]) B = np.array([[5, 6], [7, 8]])
- Use the
np.dot()
function to multiply the matrices:result = np.dot(A, B)
Please note that A * B
performs element-wise multiplication, not matrix multiplication. A + B
performs element-wise addition.
