Quadratic Eigenvalue Problem Solvers - QEP

## Quadratic Eigenvalue Problem Solvers - QEP: Examples

The Quadratic Eigenvalue Problem (QEP) solver is the object provided by SLEPc for specifying a quadratic eigenvalue problem. Apart from the specific solvers for this type of problems, there is an EPS-based solver, i.e., it uses a solver from EPS to solve a generalized eigenproblem obtained after linearization.

As in the other solver objects, users can set various options at runtime via the options database (e.g., `-qep_nev 4 -qep_type linear`). Options can also be set directly in application codes by calling the corresponding routines (e.g., QEPSetDimensions() / QEPSetType()).
