WebJun 16, 2024 · The adjugate of an matrix is defined by. where denotes the submatrix of obtained by deleting row and column . It is the transposed matrix of cofactors. The adjugate is sometimes called the (classical) adjoint and is sometimes written as . … The adjugate of A is the transpose of the cofactor matrix C of A, In more detail, suppose R is a unital commutative ring and A is an n × n matrix with entries from R. The (i, j)-minor of A, denoted Mij, is the determinant of the (n − 1) × (n − 1) matrix that results from deleting row i and column j of A. The cofactor matrix of A is the n × n matrix C whose (i, j) entry is the (i, j) cofactor of A, which is the (i, j)-minor times a sign factor: WebAdjoint of a matrix or adjugate matrix is the transpose of a cofactor matrix.
