<h2>Polynomial Eigenvalue Problem Solvers - PEP: <a href="../../../src/pep/examples/tutorials/index.html">Examples</a> <a href="../../../src/pep/examples/nlevp/index.html">NLEVP</a></h2>
<p>
The Polynomial Eigenvalue Problem (PEP) solver is the object provided by SLEPc for specifying a polynomial 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.
</p>
<p>
As in the other solver objects, users can set various options at runtime via the options database (e.g., <code>-pep_nev 4 -pep_type linear</code>).
Options can also be set directly in application codes by calling the corresponding routines (e.g., <a href="PEPSetDimensions.html">PEPSetDimensions</a>() / <a href="PEPSetType.html">PEPSetType</a>()).
