Once we have transformed to 0 all the elements except one of the chosen column, we compute the determinant of the 4×4 matrix using cofactor expansion. The cofactor expansion is a method to find determinants which consists in adding the products of the elements of a column by their respective cofactors.
14.12.2021 · What is a cofactor in matrix? The Cofactor is the number you get when you remove the column and row of a designated element in a matrix, which is just a numerical grid in the form of rectangle or a square. The cofactor is always preceded by a positive (+) or negative (-) sign. How do you find the cofactor of a 2×2 matrix?
