WebThe adjoint of a matrix B can be defined as the product of B with its adjoint yielding a diagonal matrix whose diagonal entries are the determinant det(B). B adj(B) = adj(B) B … WebTheorem. Let A be an n by n matrix. Then the following conditions hold. If A has a zero row (column) then det(A)=0.; If the last row (column) of A contains exactly one non-zero number A(n,n) then . det(A)=A(n,n)*C nnwhere C nn is the cofactor of entry A(n,n) that is the determinant of the matrix obtained by deleting the last row and the last column of matrix …
