How to Use the 2x2 & 3x3 Matrix Determinant & Transpose Calculator
-
1
Select matrix dimension: 2×2 or 3×3 grid.
-
2
Fill in the numeric matrix cells with integers or decimals.
-
3
Click "Compute Matrix Properties" to evaluate.
-
4
Inspect the Determinant det(A), Matrix Transpose Aᵀ, Matrix Trace tr(A), and Invertibility status.
Practical Example & Use Case
Evaluating 3x3 matrix [[1, 2, 3], [0, 1, 4], [5, 6, 0]] reveals det(A) = 1, confirming the matrix is non-singular and invertible.
Technical Notes & Limitations
Calculates determinants via Laplace expansion; matrices with det(A) = 0 are identified as singular with no inverse.
Frequently Asked Questions
What does a matrix determinant of zero mean?
If det(A) = 0, the matrix is singular and cannot be inverted. Its rows (or columns) are linearly dependent.
