# EPSLAPACK

EPSLAPACK = “lapack” - A wrapper to LAPACK eigensolvers.

## Notes

This is not really a full-featured eigensolver but simply an interface to some LAPACK routines [Anderson et al., 1999]. These routines operate sequentially in dense mode and therefore are suitable only for small size problems. This solver should be used only for debugging purposes.

The LAPACK routine is not called directly, instead a `DS` object of the appropriate type is set up.
