PLOTBAUMGARTNER2013 - plot probabilistic prediction matrixes

Program code:

function out = plotbaumgartner2013( p,tang,rang,varargin)
%PLOTBAUMGARTNER2013 plot probabilistic prediction matrixes
%   Usage:    plotbaumgartner2013(p,tang,rang);
%             plotbaumgartner2013(p,tang,rang,exptang,exprang);
%
%   Input parameters:
%     p       : prediction matrix containing probability mass vectors (PMVs) 
%               for the polar response angle as a function of the polar  
%               target angle (1st dim: response angle, 2nd dim: target
%               angle)
%     rang    : polar response angles
%     tang    : polar target angles
%
%   `plotbaumgartner2013(p,rang,tang)` plots predicted PMVs referring to  
%   the polar response angles *rang* as a function of the target angles 
%   *tang* with gray color coded probabilities similar to Baumgartner et al. 
%   (2002). Actual response patterns from psychoacoustic experiments can be 
%   overlayed optionally.
%
%   `h=plotbaumgartner2013(...)` additionally returns the figure handle.
%
%   `plotbaumgartner2013` accepts the following optional parameters:
%
%     'exptang',exptang   Overlay actual response patterns with the   
%                         experimetal polar target angles *exptang*.
%
%     'exprang',exprang   Experimetal polar response angles *exprang*
%                         corresponding to *exptang*.
%
%     'MarkerSize',ms     Set the marker (circles) size of the overlaying
%                         response pattern to *ms*. Default value is 6.
%
%     'cmax',cmax         Set the maximum probability of the color code to 
%                         *cmax*. Default value is 0.2.
%
%   `plotbaumgartner2013` takes the following flags at the end of the line 
%   of input arguments:
%
%     'colorbar'    Display the colorbar. This is the default.
%    
%     'nocolorbar'  Do not display the colorbar.
