Algorithms for solving infinite-dimensional non-linear eigenvalue problems, and examples.
The code is presented as a gallery of examples for producing the results of the paper
Matthew J. Colbrook, Alex Townsend, "Avoiding discretization issues for nonlinear eigenvalue problems"
Please reference this paper if you use the code.
The subfolder "inf_dim_functions" contains routines, including the infinite-dimensional version of Beyn's algorithm.
The subfolder "computed_data" contains results of the algorithm for some of the plots.
Some of the code makes use of the Chebfun software package for computing with functions, available for download at https://www.chebfun.org/ and the NLEVP collection, available for download at https://github.com/ftisseur/nlevp
