Some useful decomposition methods include QR, LU and Cholesky decomposition. The determinant of the product of matrices is equal to the product of determinants of those matrices, so it may be beneficial to decompose a matrix into simpler matrices, calculate the individual determinants, then multiply the results. For a 2-by-2 matrix, the determinant is calculated by subtracting the reverse diagonal from the main diagonal, which is known as the Leibniz formula. Some matrices, such as diagonal or triangular matrices, can have their determinants computed by taking the product of the elements on the main diagonal. This method is based on one proposed in Bare1968. This method uses both recursion and an elimination trick to assist in the calculation of the determinant. There are many methods used for computing the determinant. 2 Improved Recursive Method for Determinant Calculation Let us recall a method to calculate the determinant of a symbolic matrix that is often referred to as fraction free. Geometrically, the determinant represents the signed area of the parallelogram formed by the column vectors taken as Cartesian coordinates. A system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant this method is called Cramer's rule, and can only be used when the determinant is not equal to 0. A determinant of 0 implies that the matrix is singular, and thus not invertible. The value of the determinant has many implications for the matrix.
