\bm{v}^{(m+1)} = R \bm{v}^{(m)} - B \bm{f}$$ We also saw that the convergence of the iterative calculation is dominated by the spectral radius $${ \rho(R) }$$ of the iteration matrix $${ R }$$. In ...

In the previous articles, regarding the numerical calculation of the Poisson equation, we looked at the calculation method using the Jacobi method and the bottleneck of convergence in iterative ...

A relic from long before the age of supercomputers, the 169-year-old math strategy called the Jacobi iterative method is widely dismissed today as too slow to be useful. But thanks to a curious, ...
