# EPSEVSL

EPSEVSL = “evsl” - A wrapper to EVSL [Li et al., 2019].

## Note

The Eigenvalues Slicing Library {EVSL} is intended for the case that all eigenvalues inside a given interval are requested, for Hermitian problems. It is based on polynomial filters, and has similarities with the algorithms implemented in `STFILTER`.
