NLEVP: A Collection of Nonlinear Eigenvalue Problems

This MATLAB Toolbox provides a collection of nonlinear eigenvalue problems. It contains problems from models of real-life applications as well as problems constructed specifically to have particular properties.

The collection is fully documented in the technical report

T. Betcke, N. J. Higham, V. Mehrmann, C. Schröder, and F. Tisseur, NLEVP: A Collection of Nonlinear Eigenvalue Problems, MIMS EPrint 2008.40, April 2008.

The collection will grow and contributions are welcome; see the report for details of how to contribute. To cite the collection please cite either this web page or the technical report. BibTeX entries for both are available.

About the toolbox

• The current release is version 1.0 of the toolbox, dated April 4, 2008.
• The toolbox is provided as a zip file and a tar file, which contain the MATLAB M-files but not the technical report (for which see above). Installation instructions are in the technical report.
• The toolbox is distributed under the terms of the GNU General Public License (version 3 of the License, or any later version) as published by the Free Software Foundation.
• The toolbox has been tested under MATLAB 7.5 (R2007b) and 7.6 (R2008a). It does not work with versions 6.5 (R13) and earlier of MATLAB, since it uses functionality introduced in MATLAB 7.0 (R14).
