Online calculator to calculate 4x4 determinant with the Laplace expansion theorem and gaussian algorithm.

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. Being the i, j cofactor of the matrix defined by: Where M ij is the i, j minor of the matrix, that is, the determinant that results from deleting the i-th row and the j-th column of the matrix.
