Not able to create csv file using writetable after creating .exe file in Mac

I need to store outputs of my application to a .csv file. The *.fig file works fine and saves the outputs to the csv file as expected. But I when I use the application compiler and generate .exe file. The .exe file doesn't generate/ store the outputs to the csv file.

I was able to generate the expected outputs on windows fine. But when I did this on a Mac I am not able to get it.

I recreated my need here:

% --- Executes on button press in writeDat.
function writeDat_Callback(hObject, eventdata, handles)
% hObject    handle to writeDat (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
Names = ['NameX';'NameY';'NameZ'];
Sub1 = [23;33;43];
Sub2 = [53;63;73];
T = table(Names,Sub1,Sub2);
T.Properties.VariableNames = {'Name','Sub1','Sub2'};
try
  writetable(T, fullfile(pwd,'trialTable.csv'));
  msgbox('Sucess!');
catch
  msgbox('Fail!');
end

This is the push button for example. It works fine as expected with .fig but not after creating .exe using application compiler.

Any suggestions?

.exe never run on mac unless you have an emulator such as Parallels.

I mean the Application Kind file generated thorugh application compiler on Mac

[Walter Roberson]

Not a good idea to rely on the current directory for an executable. See the documentation of ctfroot()

[Gopichandh Danala]

Thanks, I tried defining the location manually like /Applications/XXFolder instead of pwd and it worked. ctfroot showed me a location not visibile on Mac. I am not familiar with using Mac. So, Maybe I will just stick to manual destination location for now.

Manual destination is one valid approach. Another valid approach is to uigetdir() or uiputfile() so the user can choose. A third valid approach is to examine the HOME environment variable to find the user's home directory (e.g., /Users/Gopichandh) and create the file in some location relative to that, such as

if ~ispc()
  HOME = getenv('HOME');
  apphome = fullfile(HOME, '.XXFolder');
else
  HOME = getenv('APPDATA');
  apphome = fullfile(HOME, 'XXFolder');
end
if ~exist(apphome, 'dir')
  try
    mkdir(apphome)
  catch ME
    error('Cannot create directory "%s", apphome');
  end
end
filename = fullfile(apphome, 'TrialTable.csv');

Thanks. The approach you explained using ispc, makedir is more dynamic and will be best fit for my requirement.

I think some others will have same issue as me in future. Post as an answer maybe. I will be accept so it helps others
