MATLAB: How to dynamically pause the matlab into debugging while execution by a Gui

I have a long non-gui matlab code with different function m-files which do some simulations.

I want to dynamically pause the code from running by going to the debugging mode while execution. How can I write a matlab Gui check box that from the start of the running the gui shows "go to debugging" and "continue" check boxes. As soon as I check "go to debugging" the program should go to debugging mode.

The reason is that I have some global variables and I want to stop the code from the printed results and change that variable, like in debugging mode, and then press continue for rest of execution with the new global variable.

I appreciate your help.

Create a callback function for the "go to debugging" checkbox. Inside the callback, include the command

   dbstop;

When finished debugging, simply type

   dbcont

At the command prompt.

You can use a toggle button:

buttonH = uicontrol('Sytle', 'ToggleButton', ...
             'Units',    'pixels', ...
             'Position', [5, 5, 60, 20], ...
             'String',   'Pan', ...
             'Value',    1);
while win_xlimit(2) <= xlimit_orig(2)
  set(ax_handle, 'Xlim', win_xlimit);
  pause(0.05);
  if get(buttonH, 'Value') == 1
    win_xlimit = win_xlimit + offset;
  end  
end

Do NOT do this

This would actually be horribly slow, pointlessly complex, obfuscated, and very buggy way to write your code. You would make your code hard to debug, and a pain to work with. Read this to know why:

Using indexing would be simple, neat, and very efficient. You should use one array and indexing. Indexing is the solution you should be using, because it is the most efficient way to write MATLAB code, is simple, neat, and very easy to debug. Indexing is explained quite well in the MATLAB introductory tutorials, which are highly recommended for all beginners:
