function [ varargout ] = solveeig( varargin )
%SOLVEEIG Solve eigenvalue problem.
%
% [ U, L ] = SOLVEEIG( PROB, VARARGIN ) Solves the eigenvalue
% problem described in the PROB finite element struct with
% homogenous boundary conditions, and returns the eigenvectors U and
% eigenvalues L. Accepts the following property/value pairs.
%
% Input Value/{Default} Description
% -----------------------------------------------------------------------------------
% neigs scalar/{6} Number of eigenvalues
% sigma scalar/string/{sm} Range or type of eigenvalues
% see the eigs function for options
% imass scalar/{4} Mass matrix lumping
% 1 - Full mass matrix
% 2 - row sum lumping
% 3 - diagonal lumping
% 4 - HRZ diagonal lumping
% init u0|{expr}/{0} Initial value solution or expression
% for linearization point
% solcomp {all dvars} Dep. variables/subdomains to solve for
% icub scalar/{auto} Cubature rule/order used in assembly
% Default 1+max(shape function order)
% isymm scalar/{0} Symmetrize BCs if applicable
% waitbar scalar/{0} Show waitbar
% fid scalar/{1} File identifier for output ([]=no output)
