WebDec 10, 2024 · Adjugate (also called Adjoint) of a Square Matrix. Let A = [a ij ] be a square matrix of order n and let C ij be cofactor a ij of in A. Then the transpose of the matrix of cofactors of elements of A is called the adjoint of A and is denoted by adj A. Thus, adj A = [C ij] T ⇒ (adj A) ij = C ji = cofactor of a ij in A. WebFinally, the adjugate is used to find the inverse of the matrix.
