FAQ
What does the determinant signify?
It indicates matrix invertibility and scaling factor.
Can inputs be decimals?
Yes, any real numbers are accepted.
When is the determinant zero?
When rows or columns are linearly dependent.
Additional Information
- A zero determinant means the matrix is singular.
- Positive determinant preserves orientation.
