Cofactor matrix in matlab

Web% C = cofactor(A) returns the matrix of cofactors of A. % If A is invertible, then inv(A) = C' / det(A). % % C = cofactor(A, i, j) returns the cofactor of % row i, column j of A. if nargin … WebThe co-factor matrix is formed with the co-factors of the elements of the given matrix. The co-factor of an element of the matrix is equal to the product of the minor of the element and -1 to the power of the positional value of the element. The co-factor matrix is useful to find the adjoint of the matrix and the inverse of the given matrix.
