Adjoint matrix

The adjoint matrix is defined as the transpose of the cofactor matrix. Given a matrix A of dimensions n×n, the cofactor matrix C is the matrix whose (i,j) entry is the (i,j)LaTeX(i,j) cofactor of A: Cij=(-1)i+jMij, where Mij denotes the (i,j)LaTeX(i,j) minor of A. Thus, the adjoint matrix of A is adj(A)=CT.
