Has Matlab 2013b and new fixed the memory leak issues in pause and delete?

You could say they were fixed but that would not explain the whole situation.

The pause "leak" was a message queuing and growth problem. All memory would be released when the code stopped running and MATLAB reached the command line. This has been fixed and only happened in specific unusual circumstances.

I don't believe the delete "leak" was a leak at all but is exactly the same issue as mentioned in the last comment posting by Jeremy on the page. MATLAB stores a string name for every function or file name seen forever as a performance and string management optimization.

It depends on what you deleted. If a bit of code in the .m file you’re editing, in the very top Editor taskbar near the right end, there are two curved arrows. Clicking on the one that points to the left will undelete inadvertently deleted text.

For .m files, depending on the preferences you have set (particularly autosave), you might find the complete or earlier version of it with the same prefix and an .asv (instead of .m) extension. Otherwise for a deleted .m file, on Windows machines look in the Recycle Bin. (No guarantees — I’ve not done that so I have no personal experience — but that is where I’d look.)

MATLAB: Plot pause

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
