koefaktori
Koefaktori is a term used in mathematics, specifically in linear algebra, to denote a specific value associated with an element of a matrix. It is closely related to the concept of a minor. For a square matrix A, the koefaktor of the element at position (i, j), denoted as C_ij, is calculated by multiplying the minor of that element by (-1)^(i+j). The minor of the element at position (i, j), denoted as M_ij, is the determinant of the submatrix formed by removing the i-th row and j-th column from the original matrix A. Therefore, the formula for the koefaktor is C_ij = (-1)^(i+j) * M_ij.
Koefaktori play a crucial role in various matrix operations. One of their primary applications is in the
