How to convert .m file to .exe file?

I converted .m file to .exe file using deploytool. When i run .exe file it opens with logo and just after that it close. Its not through any error or warning message. I am not able to figure out why its happening!! .m file contains classdef, in which using uicontrol i am creating GUI. Is it because i don't have any .fig file ? Thanks!

To create an exe the main file that you give it must be a function - it can either be a GUIDE GUI or just a regular function, but you cannot give it a class file.

You can create a function that uses your class and deploy that, but a class on its own doesn't do anything until you make calls to its functions or properties.

I tried calling that classdef in a function but its still not working! Its working in matlab if i run that function but after converting its not showing any GUI!

[Nipurn Gulgulia]

Is .fig file needed for converting .m to .exe file! If yes than what can i do as i don't have .fig file because i am creating GUI using uicontrol !

[Adam]

You don't need a .fig.

Do you get any error messages or anything if you run your executable from the command line (or in a log file if you created one)?

[Nipurn Gulgulia]

No, I am not getting any error or warning. In Log file its showing this-

I tried with below simple function also, i am getting same thing. It show splash screen and than close!

   function Test_1(varargin)
             GUIsize = [520   420   520   420];
             parent = figure('Name','Work Load','NumberTitle','off',...
                     'Menubar','none');
             set(parent, 'Units', 'pixels', 'Position', GUIsize);
             ProjectPanel    =  uipanel(parent, 'Title', 'Projects',...
                               'Position', [0, .01, .505,.91]);
             TimePanel       =  uipanel(parent, 'Title', 'Time Spent',... 
                               'Position',[.5, .01, .495,.91]);
             Top             =  uipanel(parent, 'Position', [0, .905, .997,.0875]);
             Add          =  uicontrol(parent, 'Units', 'norm',...
                             'Position', [0.24, 0.917, 0.11, 0.067], 'String', 'Add','FontSize', 9);
             Save            =  uicontrol(parent, 'Units', 'norm',...
                              'Position', [0.37, 0.917, 0.11, 0.067],'String', 'Save','FontSize', 9);

    end

Does your GUI use uiwait or waitfor to pause execution until the GUI is closed? If it does not, I believe what's happening is that the executable is opening your GUI and as soon as the GUI's program file finishes executing it exits, closing all figures as part of its shutdown process. [If it didn't, it would leak memory and graphics handles.] Adding uiwait or waitfor will prevent the GUI's program file from finishing until you close the GUI figure, and that would keep the executable running while you interact with your GUI.

If your GUI does use uiwait or waitfor, try launching the executable by typing its name at your operating system's command prompt rather than double-clicking on its icon. If it experiences an error on startup, that should display the message at the prompt. That may suggest a solution to you, or you can copy it into a comment on this question and that may suggest a solution to some of the people reading this discussion.

                             'Position', [0.24, 0.917, 0.11, 0.067], 'String', 'Add','FontSize', 9);
             Save            =  uicontrol(parent, 'Units', 'norm',...
                              'Position', [0.37, 0.917, 0.11, 0.067],'String', 'Save','FontSize', 9);

    end

[Steven Lord]

Yes, that's the correct and expected behavior.

When you run that function, it reaches the last line (that creates the Save uicontrol) and then the function finishes execution. Because you've finished executing the function, the standalone executable finishes and as part of its shutdown it closes any figure that it opened.

Try adding this line as the last line in your Test_1 function:

uiwait(parent)

If you do that, the standalone application will not exit until you close the figure.

[Nipurn Gulgulia]

I tried this but still the same result! I even tried with removing function and directly save the code and complied it but in all the cases i am getting same result! No error or warning message!

[Steven Lord]

I tried building the application in release R2018a using the code you posted and was able to get a running application that left the figure on screen until I closed it myself. If you're not seeing the same results, you may want to contact Technical Support and work with them to determine why your results are different from mine.
