WebI've been working on a matrix-library in C++ for a while and amongst other functions, I've implemented two functions for calculating the determinant of a matrix: Gauss-Algorithm: This algorithm is based on the fact that the determinant of a triangular matrix equals the product of it's diagonal entries. Therefore it is pretty intuitive to ... WebJun 8, 2024 · Gaussian elimination is based on two simple transformation: It is possible to exchange two equations. Any equation can be replaced by a linear combination of that row (with non-zero coefficient), and some other rows (with arbitrary coefficients). In the first step, Gauss-Jordan algorithm divides the first row by a 11 .
