How to determine application exe name at run time?

I want to determine the executable file name and path for a Matlab Compiler produced standalone application at run time. The desired result would be similar to mfilename('fullpath') but return the location of the exe file instead.

On Windows, on a computer with .Net, this may work:

args = System.Environment.GetCommandLineArgs;
fullpath = args(1);

I don't have the matlab compiler, so can't test.

Thanks to both Guillaume and Image Analyst for your answers. Really, one of the answers supplied the exe name and the other gave its path. The following code is my pieced-together implementation. It appears to be working with R2014b on Windows.

function filename = exefilename
% Determine full path to calling file
% In a deployed program, this will point to the application exe.
% In regular Matlab, it will be the calling m-file.

if isdeployed % Executable in stand-alone mode.
    [~, result] = system('path');
    exedir = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));

      args = System.Environment.GetCommandLineArgs;
      relpath = char(args(1));
      [~,exename,ext] = fileparts(relpath);
      filename = fullfile(exedir,[exename,ext]);

else % MATLAB mode.
    [st,ind] = dbstack('-completenames');
    filename = st(ind+1).file;
end
end

Why dbstack() instead of mfilename()?

See this function. Call it in your code and see what it returns.

% Returns the folder where the compiled executable actually resides.
function [executableFolder] = GetExecutableFolder() 
  try
    if isdeployed 
      % User is running an executable in standalone mode. 
      [status, result] = system('set PATH');
      executableFolder = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));
%       fprintf(1, '\nIn function GetExecutableFolder(), currentWorkingDirectory = %s\n', executableFolder);
    else
      % User is running an m-file from the MATLAB integrated development environment (regular MATLAB).
      executableFolder = pwd; 
    end 
  catch ME
    errorMessage = sprintf('Error in function %s() at line %d.\n\nError Message:\n%s', ...
      ME.stack(1).name, ME.stack(1).line, ME.message);
    uiwait(warndlg(errorMessage));
  end
  return;
