What will be the shape of the eigenvectors matrix returned by
eig for a 3x3 matrix?What will be the shape of the eigenvectors matrix returned by eig for a 3x3 matrix?
medium📝 Predict Output Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Understand eigenvectors output shape
For an n x n matrix, eig returns eigenvectors as an n x n matrix.Step 2: Apply to 3x3 matrix
So, for 3x3 input, eigenvectors shape is (3, 3).Final Answer:
(3, 3) -> Option BQuick Check:
Eigenvectors shape = (n, n) for n x n matrix [OK]
Quick Trick: Eigenvectors matrix shape matches input matrix size squared [OK]
Common Mistakes:
MISTAKES- Expecting eigenvectors as 1D array
- Confusing shape with flattened vector
- Assuming shape is (n, 1) or (1, n)
