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:
%
% 'no_plot' Don't plot, only return data. This is the default.
%
% 'plot' Plot the data.
%
% 'itd2angle_lookuptable' Return the data for the ITD-to-angle look-up.
%
% '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');
