DATA_WIERSTORF2013 - Data points from the Wierstorf (2013) book chapter

Program code:

function [data,description] = data_wierstorf2013(varargin)
%DATA_WIERSTORF2013 Data points from the Wierstorf (2013) book chapter
%   Usage: data = data_wierstorf2013_data(flag)
%
%   Output parameters:
%       data        : the data points from the given figure as columns of a
%                     matrix. The x axis is alway the first column, followed by
%                     data and for example confident intervals. Which kind of
%                     data is stored in which column is indicated by the
%                     description string.
%       description : string that describes the type and unit of the data
%                     represented in every column of the data matrix
%
%   `data_wierstorf2013(flag)` returns data points from the Wierstorf 2013 book
%   chapter. The flag may be one of:
%
%     'noplot'        Don't plot, only return data. This is the default.
%
%     'plot'          Plot the data.
%
%     'fig6'          Return data from Fig. 6. The data describes the difference
%                     between the azimuth angle of the auditory event and the
%                     azimuth angle of the sound event for different incidence
%                     angles of the sound event. The data was collected with
%                     real loudspeakers as sound events and for via binaural
%                     synthesis simulated loudspeakers as sound event.
%
%     'fig7'          Return data from Fig. 7. The data descirbes the result of
%                     a listening test measuring the localization performance
%                     for Wave Field Synthesis setups at 16 different positions
%                     in the listening area. The data comes for three different
%                     loudspeaker arrays consisting of  3, 8, or 15 loudspeakers.
%                     Note: these are the same data as from Fig. 10.
%
%     'fig10'         Return data from Fig. 10. The data descirbes the result of
%                     a listening test measuring the localization performance
%                     for Wave Field Synthesis setups at 16 different positions
%                     in the listening area. The data comes for three different
%                     loudspeaker arrays consisting of  3, 8, or 15 loudspeakers.
%                     Note: these are the same data as from Fig. 7.
%
%   If no flag is given, the function will print the list of valid flags.
%
%   Examples:
%   ---------
%
%   Figure 6 can be displayed using :::
%
%     data_wierstorf2013('fig6','plot');
%
%   Figure 7 can be displayed using :::
%
%     data_wierstorf2013('fig7','plot');
%
%   Figure 10 can be displayed using :::
%
%     data_wierstorf2013('fig10','plot');
