This calculator finds the modular inverse of a matrix using adjugate matrix and modular multiplicative inverse
The inverse $ M^{-1} $ of a square matrix $ M $ can be calculated using several methods that dCode applies for all square matrix sizes. — Calculation via transpose of the cofactor matrix: $$ M^{-1} = \frac{1}{\det M} \left( \operatorname{cof}(M) \right)^\mathsf{T} = \frac{1}{\ det M} \operatorname{comp}(M) $$
