function ex_loadsave
% This example shows how to work with the 
% "load/save" functions on data files in
% deployed mode. There are three source data files
% in this example.
%    user_data.mat 
%    userdata\extra_data.mat 
%    ..\externdata\extern_data.mat
%
% Compile this example with the mcc command: 
%     mcc -m ex_loadsave.m -a 'user_data.mat' -a
%     '.\userdata\extra_data.mat' 
%         -a '..\externdata\extern_data.mat'
% All the folders under the current main MATLAB file directory will 
%    be included as
% relative path to ctfroot; All other folders will have the 
%    folder
% structure included in the deployable archive file from root of the 
%     disk drive.
%
% If a data file is outside of the main MATLAB file path,
%     the absolute path will be
% included in deployable archive and extracted under ctfroot. For example: 
%   Data file  
%     "c:\$matlabroot\examples\externdata\extern_data.mat"
%     will be added into deployable archive and extracted to
%  "$ctfroot\$matlabroot\examples\externdata\extern_data.mat".
% 
% All mat/data files are unchanged after mcc runs. There is
% no encryption on these user included data files. They are 
% included in the deployable archive.
%
% The target data file is:
%   .\output\saved_data.mat
%   When writing the file to local disk, do not save any files 
%    under ctfroot since it may be refreshed and deleted  
%   when the application isnext started.

%==== load data file =============================
if isdeployed
    % In deployed mode, all file under CTFRoot in the path are loaded
    % by full path name or relative to $ctfroot.
    % LOADFILENAME1=which(fullfile(ctfroot,mfilename,'user_data.mat'));    
    % LOADFILENAME2=which(fullfile(ctfroot,'userdata','extra_data.mat'));
    LOADFILENAME1=which(fullfile('user_data.mat'));
    LOADFILENAME2=which(fullfile('extra_data.mat'));
    % For external data file, full path will be added into deployable archive;
    % you don't need specify the full path to find the file.
    LOADFILENAME3=which(fullfile('extern_data.mat'));
