Also I got error for " imM=im>80;" in pushbutton2 function
Code:
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
[fname path]=uigetfile('*.jpg');
fname=strcat(path,fname);
im=imread(fname);
im=rgb2gray(im);
axes(handles.axes1)
imshow(im);
title('Grayscale Iris Image');
% --- Executes on button press in pushbutton2. function pushbutton2_Callback(hObject, eventdata,handles)
imM=im>80;
axes(handles.axes2)
imshow(imM);
title('Threshold Image');

I answered this already in your other question. Basically, see the FAQ http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F to see a variety of ways how you can get "im" into that function.

I guess you didn't want to read the FAQ, or didn't understand it. If you didn't understand it, probably the simplest approach for you is to simply put
global im;
as the first line of every function where you expect to use im. Just be aware that if you change it in any function, it's global so it will change in all functions from that point in time onwards. Functions that have that global line will see im, and functions that don't have that line won't see im.
