I have a gui that performs an xlswrite function and creates a file called summary.xlsx in a folder. When I turn this into an executable I want the current directory of that executable to replace that filepath in xlswrite. What does this code look like?

GetExecutableFolder.m

For Windows, the attached function works to find the "real" folder where the executable is, which is not where mfilename says it is.

Would the xlswrite code ultimately look like:

    % 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; 
    filename=[pwd,'Summary.xlsx']
    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;
 %Later in my code
    xlswrite(filename,DataSummary,1,'A2')

No. You'd do something like

executableFolder] = GetExecutableFolder();
%Later in my code
fullFileName = fullfile(executableFolder, 'DataSummary.xlsx');
xlswrite(fullFileName , DataSummary,1,'A2')
