grapg is not activate plz help me

function mornig

global A F T;
N=500;

handles.fig=figure;
mpos=get(handles.fig,'position');
set(handles.fig,'position',[mpos(3) mpos(4) N M]);

handles.axes=axes();
set(handles.fig,'unit','pixels');
set(handles.axes,'unit','pixels');

set(handles.edit2, 'callback', {@edit_callback2, handles,F});
set(handles.edit3, 'callback', {@edit_callback3, handles,T,A,F});

function edit_callback1(gcf, event_data, handles, A)
handles.text1=get(handles.edit1,'string');
A=(handles.text1);

function edit_callback2(gcf, event_data, handles, F)
handles.text2=get(handles.edit2,'string');
F=(handles.text2);

function edit_callback3(gcf, event_data, handles, T, A, F)
handles.text3=get(handles.edit3,'string');
T=(handles.text3);

plot(handles.axes,T,A*cos(2*pi*F*T));

write amplitud , freuency, time

and drawing but activate do not..

help me

function mornig

A = 0; F = 0; T = 0;     %not global!

N=500;
M=300;

handles.fig=figure;

mpos = get(handles.fig,'position');
set(handles.fig, 'position',[mpos(3) mpos(4) N M]);

handles.axes = axes();
set(handles.fig,'unit','pixels');
set(handles.axes,'unit','pixels');

handles.edit1 = uicontrol('style','edit');
set(handles.edit1,'position',[N-360 0 120 20]);
set(handles.edit1,'string','A');
set(handles.edit1,'horizontalalignment','center');

handles.edit2 = uicontrol('style','edit');
set(handles.edit2,'position',[N-240 0 120 20]);
set(handles.edit2,'string','F');
set(handles.edit2,'horizontalalignment','center');

handles.edit3 = uicontrol('style','edit');
set(handles.edit3,'position',[N-120 0 120 20]);
set(handles.edit3,'string','T');
set(handles.edit3,'horizontalalignment','center');

set(handles.edit1, 'callback', @edit_callback1);
set(handles.edit2, 'callback', @edit_callback2);
set(handles.edit3, 'callback', @edit_callback3);

%now nested functions

function edit_callback1(src, event_data)
  A = str2double( get(src, 'String') );
end

function edit_callback2(src, event_data)
  F = str2double( get(src, 'String') );
end

function edit_callback3(src, event_data)
  T = str2num( get(src, 'String') );    %because it probably is not a scalar

    plot(handles.axes, T, A*cos(2*pi*F*T));
  end

Note that in order for you to see much, you will need to enter a vector of values for T

thanks but is not to work T.T...

??? Error: File: mornig.m Line: 40 Column: 4
The function "edit_callback3" was closed
 with an 'end', but at least one other function definition was not.
 To avoid confusion when using nested functions,
 it is illegal to use both conventions in the same file.

Ah, you need to put another "end" after everything I posted.

thanks a lot... thanks!!..
