function out = plot_langendijk2002( p,rang,tang,varargin)
%plot_langendijk2002 plots pdf-matrixes with gray colormap according to Langendijk et al. (2002)
%   Usage:  plot_langendijk2002(p,rang,tang);
%
%   Input parameters:
%     p       : pdf-matrix for all target and response positions
%     rang    : response angles
%     tang    : target angles
%
%   PLOT_LANGENDIJK2002(p,rang,tang) plots predicted probability mass vectors
%   as a function of response angles rang and target angles tang with
%   gray color coded probabilities similar to Langendijk et al. (2002).
%
%   h=PLOT_LANGENDIJK2002(...) additionally returns the figure handle.
%
%   plotlagendijk 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.
