WebHere is the determinant of the matrix by expanding along the first row: - + - The product of a sign and a minor is called a cofactor. Even when there are many zero entries, row reduction is more systematic, simpler, and less prone to error. Row reduction on a determinant uses the three elementary row operations. WebAug 24, 2024 · The matrix of cofactors is moderately well posed, even when the matrix is itself singular. Of course, what you would do with it is your choice. But the simple answer is to just use loops, since each element of the matrix of cofactors is itself just a lower order determaint. But why, when we already have adjoint?
