function plotsinorcos
global Am t fr cs S;
N=500;
M=300;
t=[0 : 0.01 : 5];
handles.fig=figure();
mpos=get(handles.fig,'position');
set(handles.fig,'position',[mpos(3) mpos(4) N M]);
set(handles.fig,'units','pixel');
handles.axes=axes();
set(handles.axes,'units','pixel');
handles.edit1=uicontrol('style','edit');
set(handles.edit1,'position',[N-50 0 50 20]);
set(handles.edit1,'string','amplitude');
set(handles.edit1,'horizontalalignment','left');
handles.edit2=uicontrol('style','edit');
set(handles.edit2,'position',[N-120 0 70 20]);
set(handles.edit2,'string','frequency');
set(handles.edit2,'horizontalalignment','left');
handles.edit3=uicontrol('style','edit');
set(handles.edit3,'position',[N-200 0 80 20]);
set(handles.edit3,'string','sin=1,cos=2');
set(handles.edit3,'horizontalalignment','left');
set(handles, 'callback', {@callbcak, handles,Am,fr,S,cs});
function callbcak(gcf, event_data, handles, Am,fr,S,cs)
handles.text1=get(handles.edit1,'string');
handles.text2=get(handles.edit2,'string');
handles.text3=get(handles.edit3,'string');
Am=handles.text1;
fr=handles.text2;
cs=handles.text3;
if cs==1
      S=Am*cos(2*pi*fr*t);
elseif cs==2
      S=A*cos(2*pi*fr*t);
end
handles.plot1=plot(t,S);
hello! i want cos , sin plot 
handles.edit<< i write = amplitude,frequency and cos=1,sin=2

resultingly draw handles.plot1

plz help me..

Why not make it easy on yourself? Use GUIDE so that you don't have to build a complete user interface from tedious and detail very low level routines. Get started with MAGIC, a nice framework that will get you started.

Description

This GUI will help the novice user get up to speed very quickly on using GUI-based applications. Everything is laid out in a very simple Step 1, Step 2, Step 3, etc. layout. It is a very good starting point for a typical application. This application uses GUIDE to do the user interface design, and has most of the basic controls such as buttons, listboxes, checkboxes, radio buttons, scrollbars, etc. It allows the user to select a folder of images, select one or more images and display them, to select a series of options, and to individually or batch process one or more images.
