We'll look at how to use SciPy to numerically solve linear systems corresponding to square matrices. We'll also look at how to implement row operations (Gaussian elimination). First we import the ...

The method is an iterative method which uses upwind difference for discretization and uses Gauss-Seidel iterations with alternating sweeping ordering to solve the discretized system, The crucial idea ...

The aim was to teach the formal solving method, which involved performing the same operations on both sides of the equation using, notably, the balance model. Analysis of students' reasoning showed ...
