calculateSoundVelocity.m

function [calculatedSoundVelocity] = calculateSoundVelocity(pTemperature, pPressure, pMethod, pSoundSource)
%CALCULATESOUNDVELOCITY Calculates the sound velocity based on the given values.
%   Parameters:
%       pTemperature    The temperature array.
%       pPressure       The pressure array.
%       pMethod         The chosen method. Available methods are:
%                       del grosso
%                       linear
%                       soundsource
%       pSoundSource    The sound source data. Only required if pMethod is
%                       set to soundsource.
%
%   Returns:
%       The calculated sound velocity in m/s.
