Added

  • Added a directory contrib to include code contributed by users. It is not formally a part of the Spectra library, but it may contain useful solvers and applications based on Spectra. Code in contrib may not be fully tested, so please use with caution. Feedback and report of issues are always welcome
  • Added an eigen solver LOBPCGSolver in the contrib directory using the LOBPCG algorithm, contributed by Anna Araslanova
  • Added a partial SVD solver PartialSVDSolver in the contrib directory
  • Added two internal classes Arnoldi and Lanczos to compute the Arnoldi/Lanczos factorization in eigen solvers
  • Added a few other internal classes to refactor the eigen solver classes (see below)

Changed

  • API change: Spectra now requires Eigen >= 3.3
  • API change: The library header files are moved into a directory named Spectra. Hence the recommended include directive would look like #include <Spectra/SymEigsSolver.h>
  • All eigen solvers have been refactored using a cleaner class hierarchy. It may potentially make the implementation of new eigen solvers easier, especially for generalized eigen problems
  • The matrix operation classes (e.g. DenseSymMatProd and SparseSymMatProd) are now internally using an Eigen::Ref object to wrap the user matrices, thanks to Dario Mangoni who raised this issue in #16
  • Fixed inappropriate range of random numbers in the tests
