# Adjoint matrix

This tool calculates the Adjoint matrix of A.

## Adjoint Matrix

The adjoint matrix, also called adjugate matrix, is the transpose of the comatrix (Cofactor matrix). If M is a square matrix, then its adjoint (adjugate) matrix denoted 'Adj(M)' is equal to,

\(\text{Adj}(M) = \text{com}(M)^T\)

where com(M) is the Cofactor matrix of M.
