WebJul 1, 2024 · In this paper, a fast HSS-based algorithm has been proposed and applied to solve systems of nonlinear equations. The new scheme is an outer/inner iteration method. In our numerical example, the number of outer iterations in the new algorithm is less than or equal to half of outer iterations in the NHSS scheme. WebA 1 − 1 = B 1. A 2 − 1 = B 2. The next step is to put them back together, that is done with the help of the so called "Thevenin Matrix" (in our case it is …
