Matthias<p>Just finished the &quot;beta&quot; of my javascript sparse matrix solver. For testing, I first created a 20000 x 20000 sparse test matrix A and the vector c. Solving the equation Ab=c took 20 seconds. Quite feasible for a javascript code I guess. With the solver I want to carry out some finite element analysis in a web browser.<br /><a href="https://nerdculture.de/tags/StructuralEngineering" class="mention hashtag" rel="tag">#<span>StructuralEngineering</span></a> <a href="https://nerdculture.de/tags/FiniteElementMethod" class="mention hashtag" rel="tag">#<span>FiniteElementMethod</span></a> <a href="https://nerdculture.de/tags/NumericalMethods" class="mention hashtag" rel="tag">#<span>NumericalMethods</span></a> <a href="https://nerdculture.de/tags/javascript" class="mention hashtag" rel="tag">#<span>javascript</span></a></p>
