回答： Ka Mirul 2018-11-25

this is my code. when i press signal1_pushbutton--> output signal will appear. similarly,signal2_pushbutton. now i wan to stop the signal by using stop push button.

these are the conditions, i want to satisfy:-

press signal1---stops the signal by using stop button. 
lly, signal2.  
But when i press signal2 after signal1, the stop button shoulde be able(on) state, but it wont respond!!!

how can i do that? suggestions are appreciated!

 function varargout = trail1(varargin)
 % TRAIL1 MATLAB code for trail1.fig
 %      TRAIL1, by itself, creates a new TRAIL1 or raises the existing
 %      singleton*.
 %
 %      H = TRAIL1 returns the handle to a new TRAIL1 or the handle to
 %      the existing singleton*.
 %
 %      TRAIL1('CALLBACK',hObject,eventData,handles,...) calls the local
 %      function named CALLBACK in TRAIL1.M with the given input arguments.
 %
 %      TRAIL1('Property','Value',...) creates a new TRAIL1 or raises the
 %      existing singleton*.  Starting from the left, property value pairs are
 %      applied to the GUI before trail1_OpeningFcn gets called.  An
 %      unrecognized property name or invalid value makes property application
 %      stop.  All inputs are passed to trail1_OpeningFcn via varargin.

Please explain "is not working as i want" with details. We cannot guess, what you want and what you observe. Providing details is much better than a meaningless bumping by a dummy comment or by adding comments to other questions to advertise your own one.

What exactly does "stops the signal" mean?

Ram 2018-2-20

testgui.PNG

As per attached graph, when i press start button the signal is moving like a animated curve. when i press stop push button, the signal should be stop. likewise, attack signal(noise or any other signal) also should work. And also, when i press in the sequence start-->attack---> stop button should not respond. i written 'if else loop' to execute above requirements, stop button is not responding for two buttons. and also there is no error occurring while running my code. calling function is working or not here?? and sorry for posting in another question.

See attached demo where you can use the pushbutton to start or stop a process.

@Image Analyst, How can i call stop button to stop the signal when the stop signal is pressed.

 % --- Executes on button press in sine.
 function sine_Callback(hObject, eventdata, handles)
 % hObject    handle to sine (see GCBO)
 % eventdata  reserved - to be defined in a future version of MATLAB
 % handles    structure with handles and user data (see GUIDATA)
 cla;
 x=0:0.1:100;
 f=sin(x);
 y=f+sqrt(x).*randn(size(x))+1; %signal+noise
 curve = animatedline;
 set(gca,'XLim',[0 100],'YLim',[-1 1]);
 grid on;
 for i = 1:length(x)
    addpoints(curve, x(i), y(i));
    drawnow 
 end

Below code, sine wave continuously viewing @ output. when i press stop button it stops only after reaching its max. x-axis(1000 sec). otherwise the loop will continue.

How can i stop the signal in middle for example 30 or 50 or any time as per pushed the stop button.

 % --- Executes on button press in random.
 function sine2_Callback(hObject, eventdata, handles)
 % hObject    handle to random (see GCBO)
 % eventdata  reserved - to be defined in a future version of MATLAB
 % handles    structure with handles and user data (see GUIDATA)
 cla;
 set(handles.stop, 'userdata', 0);
 while(1)
    x=0:0.1:100;
    f=sin(x);
    comet(f);
  if get(handles.stop, 'userdata') % stop condition
   break;
  end
end
% --- Executes on button press in stop.
function stop_Callback(hObject, eventdata, handles)
% hObject    handle to stop (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
set(handles.stop, 'userdata', 1)

Can you attach the .fig file and .m file and any other files necessary to run it and then tell me what I have to do to start and stop the process.
