The software requires expensive additional toolboxes (at least for R2012a) for the functions betapdf(), lgamma() and normpdf(). There are free versions of these functions that use the same GPL as this project. Including these would support additional users. One could either add these as direct replacements (though they may or not be as optimized as builtin functions) or put them in an 'extra' folder that is added to the path if and only if the proprietary functions are not found:

function addGplFcns 
%adds path to 'extra' if functions not found betapdf(), lgamma() and normpdf()
% Matlab only supplies these with expensive toolboxes.
% The 'extra' folder holds GPL versions of these functions

if exist('betapdf','file') &&  exist('lgamma','file') && exist('normpdf','file'), return; end;
%at least one function missing
fprintf('x');
extPath = fullfile(fileparts(mfilename('fullpath')), 'extra'); % get the full path to this function, strip away 'ft_defaults'
if ~exist(extPath, 'dir'), warning('Unable to find folder %s', extPath); end;
addpath(extPath);

Current software fails on older versions of Matlab. This can be fixed by changing line 86 of plotPsych from if verLessThan('matlab', 'R2013a') to read if verLessThan('matlab', '8.1'), to match the expectation of verLessThan : VERSION must be a string in the form 'major[.minor[.revision]]'.

ans = 7.14.0.739 (R2012a)
