WebMar 12, 2024 · I tried to solve a linear equation using Gauss-Seidel method and execute it in MATLAB. To solve a lower triangular matrix inversion in the Gauss-Seidel method, I use 2 different approaches: 1) Forward/Backward substitution method, 2) Series of matrix multiplication or we called it Neumann series. Web2)Solve Ly = b with forward substitution. 3)Solve Ux = y with backward substitution. That is, we solve L(Ux) = b for Ux then solve for x from that. You already know how to do this from linear algebra - Gaussian elimination! 7/39 ra16036
