concatenate multiple files listed in ListBox using PushButton

Hi I have imported and listed multiple files in listbox (e.g.3 files, fullpath and filename are listed e.g.'C:\Users\file1.mat'). By clicking on the pushbutton, 3 listed files shall be concatenated to a single files.

for i=1:3  
    fileimportpath(i)= get(handles.listbox3,'String');
    fid=fopen(fileexportpath,'a');
    fprintf(fid,'%4.3f  %2.5f  %2.5f\r\n',A,B,C);
end
fclose('all');

Currently, this script encountered problem in reading the 'fileimportpath'. May I know what is the solution for it?

Thanks!

fileimportpath = get(handles.listbox3, 'String');
for i = 1 : 3
  fid = fopen(fileimportpath{i}, 'a');
  fprintf(fid,'%4.3f  %2.5f  %2.5f\r\n',A,B,C);
  fclose(fid);
end
