DATA_ZIEGELWANGER2013 - Data from Ziegelwanger and Majdak (2013)

Usage:

data = data_ziegelwanger2013(flag)

Description:

data_ziegelwanger2013(flag) returns results for different HRTF databases from Ziegelwanger and Majdak (2013).

The flag may be one of:

`'ARI'`	ARI database. The output has the following fields: `data.results` and `data.subjects`.
`'CIPIC'`	CIPIC database. The output has the following fields: `data.results` and `data.subjects`.
`'LISTEN'`	LISTEN database. The output has the following fields. `data.results` and `data.subjects`.
`'SPHERE_ROT'`	HRTF sets for a rigid sphere placed in the center of the measurement setup and varying rotation. The output has the following fields: `data.results`, `data.subjects`, `data.phi`, `data.theta` and `data.radius`.
`'SPHERE_DIS'`	HRTF sets for a rigid sphere with various positions in the measurement setup. The output has the following fields: `data.results`, `data.subjects`, `data.xM`, `data.yM`, `data.zM` and `data.radius`.
`'NH89'`	HRTF set of listener NH89 of the ARI database: The output has the following fields: `data.hM`, `data.meta` and `data.stimPar`.
`'cached'`	Reload previously calculated results from the cache
`'redo'`	Recalculate the results

The fields are given by:

`'results'`	Results for all HRTF sets
`'subjects'`	IDs for HRTF sets
`'phi'`	Azimuth of ear position
`'theta'`	Elevation of ear position
`'radius'`	sphere radius
`'xM'`	x-coordinate of sphere center
`'yM'`	y-coordinate of sphere center
`'zM'`	z-coordinate of sphere center
`'data'`	SOFA object

Requirements:

SOFA API from http://sourceforge.net/projects/sofacoustics for Matlab (in e.g. thirdparty/SOFA)
Optimization Toolbox for Matlab
Data in auxdata/ziegelwanger2013

Examples:

To get results from the ARI database, use:

data=data_ziegelwanger2013('ARI');
