Matrix Determinant & Inverse (2x2 / 3x3) Calculator
Calculates matrix determinant and inverse for 2x2 and 3x3.
Info
With this tool you can calculate for a 2x2 or 3x3 matrix: - The determinant (det(A)) - The inverse A^{-1} (if it exists) Important: - If det(A) = 0, the matrix is non-invertible (singular). - If det(A) is very close to 0, results may be numerically sensitive (ill-conditioned matrix).
