I design a gui interface and I want to use it with matlab compiler(deploytool). Data which is added previously is working correctly but when I want to add new data to gui , nothing is changing. I am not uploading new data. Only input_data matrix obtains in file also it is what I add. But I am not displaying it in gui surface. Can I add new data to programme? Following code is my loading code. Thank you in advance.

 if true
     function load_text_file_Callback(hObject, eventdata, handles)
[filename1,filepath1]=uigetfile({'*.txt*';'*.mat'});
length_fn=length(filename1);
st_pt=length_fn+1-4;
file_ext=filename1(st_pt:length_fn);
   file_ext == '.txt' % if the file is a text file
fid_airflow = fopen(fullfile(filepath1, filename1));
input_data= textscan(fid_airflow,'%d');
fclose(fid_airflow);
input_data = double(cell2mat(input_data)); % this does not
end
save ('input_data.mat','input_data')
load('input_data')
end
