EXP_JELFS2011 - Figures from Jelfs et al. (2011)

Program code:

function output = exp_jelfs2011(varargin)
%EXP_JELFS2011  Figures from Jelfs et al. (2011)
%   Usage: output = exp_jelfs2011(flag);
%
%   `exp_jelfs2011` reproduces result from the paper Jelfs et al. (2011).
%
%   The following flags can be specified;
%
%     'plot'     plot the output of the experiment. This is the default.
%
%     'noplot'   Don't plot, only return data.
%
%     'fig4'     Reproduce Fig. 4. The generated data is compared against
%                data from Hawley et at. (2004). 
%
%   Examples:
%   ---------
%
%   To display Figure 4 use :::
%
%     exp_jelfs2011('fig4');
