This article describes a formula to compute the determinant of a 4-by-4 matrix using minors and cofactors of a matrix.
To compute the determinant of matrix first one row or column is choosen. The sum of the four corresponding values of the row or column multiplied by the related cofactors results in the determinant:
Example: determinant of a 4-by-4 matrix
