%Runs multiple simulation from Matlab varying one Comsol
%paramter and storing the results in .mph files
% Mendatory inputs:
% parameterName: Identifyer of the parameter [char row vector]
% parameterValues: Array of values for the paramter [Numeric vector or cellstring]
%
% Options(default):
% parameterUnit (''): Unit used for all parameter values [char row vector]
% resultFolder (same as original model): Folder where results are to be stored [char row vector]
% showProgress (false): Enable/disable Comsol UI that shows simulation progress [boolean]
%
% Output:
% resultPath: Folder where result files are stored
%
% The simulation results are stored in .mph files with
% filenames based on the original filename and the parameter
% values (e.g. C:\modelPath\modelName_parameterName_-3[s]_result.mph).
% WARNING:
% There is a bug in Comsol where the model path which is
% provided by the Matlab Livelink classes does not match the
% real filepath. This occurs when copying a Comsol model to
% another directory, renaming it or also using "Save As" in
% Comsol. The model path in Matlab will still be the original
% one and so the results will be stored there!
