Matrix Inverse Calculator

Find the inverse of a 2×2 or 3×3 matrix instantly. Use it when solving linear systems, transforming coordinates, or computing solutions in engineering and computer graphics.

Element a (1,1)

Element b (1,2)

Element c (2,1)

Element d (2,2)

Fill in the required fields to see your result.

Linear Algebra

3x3 Matrix Trace Calculator

Compute the trace of a 3×3 matrix as the sum of its diagonal entries: a11 + a22 + a33. The trace equals the sum of eigenvalues and is invariant under similarity transformations.
