How can i Pass a file name as input or argument to matlab standalone executable

My Matalab code reading inputs from '.csv' files. These files will be generated from 'data manager'. here the issue is, file name and file locations will be different every time when data manager runs ( This is to avoid the clash) So, The compiled matlab(EXE) needs to be able to run in any folder and take input file as an argument.

help me in resolving this .... Thanks Sunil Patil

Often this would be handled with uigetfile() for interactive file selection. However, taking a filename as an argument has its advantages.

The function that you designate as the "main" one to compile should accept varargin . When nargin > 0 then each varargin{K} is a string that was passed on the command line. For example,

   function managedata(varargin)
     if nargin > 1
       filename = varargin{1};
       pathstr = cd();
     else
       [filename, pathstr] = uigetfile('Which file?');
     end
     fullname = fullfile(pathstr, filename);

Thanks for your replay.. But Here, Data manger create a temporary folder to run the Matlab EXE for each run and it will be different for each run to prevent any clashes ... So, My matlab exe should take that argument as input @ every run And There won't be user interface to select file location & name.

And,: Matlab exe shold read the '.bat' files which are generated from 'Data manager' and take those argument as input to search 'input file'

[Walter Roberson]

function managedata(batfilename, varargin)
  if ~exist(batfilename, 'file')
    error because file does not exist
  end
  fid = fopen(batfilename,'rt');
  while true
    thisfile = fgetl(fid);
    if ~ischar(thisfile); break; end   %end of file
    %now process thisfile
  end
  fclose(fid);
