Algorithmic roadmap
haampie opened this issue · comments
Open issues:
- Deflation
- Early locking (#71) --- implemented via Krylov-Schur
- Purging / removing eigenvalues that are unwanted (http://www.netlib.org/utk/people/JackDongarra/etemplates/node232.html). Plus: determining if an eigenvalue is unwanted (#80) --- implemented via Krylov-Schur
- Reordering of the Schur form such that eigenvalues closest to the specified target appear first (more or less covered by #71)
- B-inner product for generalized problems (#50)
- Tricks: improve eigenvector approximation in certain spectral transformations (http://www.netlib.org/utk/people/JackDongarra/etemplates/node233.html)
Finished:
- Handle close-to-0 eigenvalue better; stopping criterion is probably to strict for them now. (#72)
