The following definitions apply to a square matrix

$A\text{.}$

matrix of cofactors: the matrix obtained by replacing all the entries of $A$ with the corresponding cofactors of $A\text{,}$ denoted $C_A$
(classical) adjoint matrix: the transpose of the matrix of cofactors of $A\text{,}$ denoted $\adj A$
