What is the issue with this code snippet?
import numpy as np
from scipy.linalg import inv
matrix = np.array([[1, 2, 3], [4, 5, 6]])
inverse = inv(matrix)
print(inverse)
AThe import statement for inv is incorrect
BThe matrix is not square, so it cannot be inverted
CThe matrix contains non-numeric values
DThe print statement syntax is invalid
Step-by-Step Solution
Solution:
  1. Step 1: Check matrix shape

    The matrix is 2x3, which is not square.
  2. Step 2: Understand inverse requirements

    Only square matrices can have inverses.
  3. Final Answer:

    The matrix is not square, so it cannot be inverted -> Option B
  4. Quick Check:

    Verify matrix dimensions before inversion [OK]
Quick Trick: Only square matrices have inverses [OK]
Common Mistakes:
MISTAKES
  • Trying to invert non-square matrices
  • Ignoring matrix shape errors
  • Assuming all matrices are invertible
