Given an n × n matrix , the determinant of A, denoted det(A), can be written as the sum of the cofactors of any row or column of the matrix multiplied by the entries that generated them. In other words, defining then the cofactor expansion along the j th column gives: WebThe first-order leading principal minor D 1 is the determinant of the matrix obtained from A by deleting the last two rows and columns; that is, D 1 = 3.
