Adjoint of a Matrix Definition. The adjoint of a square matrix A = [a ij] n×n is defined as the transpose of the matrix [A ij] n×n , where A ij is the cofactor of the element a ij. In other words, the transpose of a cofactor matrix of the square matrix is called the adjoint of the matrix. The adjoint of the matrix A is denoted by adj A.The co-factor of the element is denoted as Cij C i j. If the minor of the element is M ij M i j, then the co-factor of element would be: Cij = (−1)i+j)M ij C i j = ( − 1) i + j) M i j.
