hiii frns....... i have been working on my project... in this i have a long continuous programme of plotting a data.. but problem is while the for loop is executing i cant stop it with my reset button.. pls help me out.. here is the programme code..

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

As you can see also, it is nearly impossible to read your code. Please use a correct formatting, if you post here. It is a good idea also to omit all running code and concentrate on the part causing the problem only. I simply cannot find the mentioned FOR loop within 20 seconds and decide to care for another thread.

Are you talking about this FOR loop:

for j=0:1:400
end guidata(hObject, handles);

There is nothing in the body of that loop! How could you know whether you are able to stop that loop or not, when on even the slowest computer that loop has to run in just a tiny fraction of a second? Please format your question properly, then clarify your question and give more details.

Here's a program that I did that uses buttons to control a loop, although right now I don't recommend the use of global variables (I learned to avoid them whenever possible) it does work, please see the code for http://www.mathworks.com/matlabcentral/fileexchange/29618-spspj
