# KELVASA2015_CALIBRATEMAPPING - Produces necessary mappings for localization model

## Usage

[mappingData] = kelvasa2015_calibratemapping(varargin)


## Input parameters

 varargin structure with all parameters required for model. If this is not included, default paramters are loaded.

## Description

The output structure "mappingData" has the following fields:
calibHRTFsig :
NxMxS matrix of signal levels in which N is the range of azimuthal angles overwhich the signal was computed, M is the number of time samples,and S are audio channels.
calSpikeDiffPerNeuronPerAzi :
NxMxS matrix of chan2 - chan1 spike rate differences in spikes/sec in which N is the range of azimuthal angles overwhich the signal was computed, M is the number of simulated AN fibers, and S is the number of time bins.
calSpikeRatePerNeuronPerLevel:
NxM matrix of spike rates in spikes/sec in which N is a range of signal levels in dB SPL and M is the number of simulated AN fibers
calParameters :
structure of model paramters used in processing calibration stimulus

kelvasa2015_calibratemapping(varargin) processes a user specified calibration wavfile and extracts the necessary data required to map simulated bilateral neural outputs onto a predicted azimuthal angle. This function computes data required by all three localization models described in (Kelvasa & Dietz(2015)) and can therefore take several hours to process.
