ST_FILTER_FILTLAN#
The polynomial filter is built with FILTLAN (Filtered Lanczos).
Note#
This filter implements the Filtered Lanczos method [Fang and Saad, 2012]. In fact, the implementation adapts files from the FILTLAN package by the same authors, which have been converted for a native integration in SLEPc.
