One of the main outputs of the research conducted within the DyCon ERC Project is the development of new computational methods and tools (algorithms, tutorials, sample codes, software, numerical simulations), all of which are constantly being integrated within our computational platform. What makes the Jacobi and Gauss-Seidel methods work? These methods do not always work. However, there is a class of square matrices for which we can prove they do work. This is the class of strictly diagonally dominant matrices. One should alos have hope that the method will converge if the matrix is diagonally dominant.

Seidel.m: A script that lets you apply Jacobi's method to a \(5 \times 5 \) matrix, much like Seidel did by hand. Fortunately, you only indicate the off-diagonal element to zero out. Matlab then does the rest.
