<h2>Quadratic Eigenvalue Problem Solvers - QEP: <a href="../../../src/qep/examples/tutorials/index.html">Examples</a></h2>

<p>
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.
</p>
<p>
As in the other solver objects, users can set various options at runtime via the options database (e.g., <code>-qep_nev 4 -qep_type linear</code>).  
Options can also be set directly in application codes by calling the corresponding routines (e.g., <a href="QEPSetDimensions.html">QEPSetDimensions</a>() / <a href="QEPSetType.html">QEPSetType</a>()).
