pep | - the polynomial eigensolver context | |
extraction | - the extraction technique |
-pep_ciss_extraction | - Sets the extraction technique (either 'ritz', 'hankel' or 'caa') |
If the 'hankel' or the 'caa' option is specified (PEP_CISS_EXTRACTION_HANKEL or PEP_CISS_EXTRACTION_CAA), then the Block Hankel method, or the Communication-avoiding Arnoldi method, respectively, is used for extracting eigenpairs.
