MATLAB: How to stop a for loop execution from GUI?(From Toolbar stop button)

MATLABmatlab gui

I have for loop,,I want to to stop this loop from a toolbar button,, Initially I have set a flag "STOP=0",,,and when I press my stop button in tool bar,,I am calling a function,,where "STOP=1" I have written script,,,,But my script is not considering this"STOP" flag,,,please hep me out>…

You can write your flag in the UserData-property of the toolbaricon.

...
set(handles.uitoolbar1,'UserData',0)
for ...
  if get(handles.uitoolbar1,'UserData')
      break
  end
end
...
function uipushtool1_ClickedCallback(hObject, eventdata, handles)
set(handles.uitoolbar1,'UserData',1)

MATLAB: Stop timer

Your timer function @axes1.handles is completly invalid, it's no function.

Also the way you start and stop the timer isn't correct, should give you too many errors.

Here's a GUI that I made with GUIDE, the fig file is just one axes and one pushbutton, the m file code is:

function varargout = rottest(varargin)
% ROTTEST M-file for rottest.fig
%      ROTTEST, by itself, creates a new ROTTEST or raises the existing
%      singleton*.
%




%      H = ROTTEST returns the handle to a new ROTTEST or the handle to
%      the existing singleton*.
%
%      ROTTEST('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in ROTTEST.M with the given input arguments.
%
%      ROTTEST('Property','Value',...) creates a new ROTTEST or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before rottest_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to rottest_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
