Sheet metal forming matrices, Olaf Schenk, Univ. of Basel. Univ. of Basel collection, Olaf Schenk (semiconductors, sheet metal forming problems, and non-linear optimization) http://www.computational.unibas.ch/computer_science/scicomp/matrices The following restriction applies (see the above web site): ------------------------------------------------------------------------------- Sparse Matrix Collection University of Basel ------------------------------------------------------------------------------- This page contains links to test data that we used to test our iterative and direct parallel solvers projects. Within these projects, new parallel algorithms and software for the solution of sparse systems of linear equations will be developed. These include algorithms for direct solution, iterative solution based on multilevel and domain decomposition methods, and for preconditioning.
