i want to load a mat file which contains neural network object file using a pushbutton; but the problem is after using uigetfile command; i don't know how to use it or share it among different gui callbacks.
Plz tell me the next steps to share among different callbacks.

Put the call to UIGETFILE in the callback for the pushbutton. Then immediately after the return, simply use the open the file as usual.

here is my code;
Plz tell me whats wrong: I am new to GUI (programming); i want to load a "net0" named varialble and use it in other callback function "Rcrd_and_Recog".
Note: i am not using GUIDE GUI; using programming GUI.
function ASR()
figure('Name','Automatic Isolated Speech Rcognition System',.......
'Menubar','none',........
'Color',[1 1 1]);
Rcrd_and_Recog =uicontrol('Style','pushbutton',....
'Units','normalized',....
'Position',[0.75 0.75 0.20 0.05],....
'String','START',....
'Callback',@Record_Recog);
LD_net = uicontrol('Style','pushbutton',....
'Units','normalized',....
'Position',[0.75 0.65 0.20 0.05],....
'String','LOAD THE NET',....
'Callback',@load_net);
function load_net(varargin)
[file path]=uigetfile('*.mat','Select the M-file');
if ~isequal(file, 0)
L=load(fullfile(path,file));
handles.net=L;
end
function Record_Recog(varargin)
fs=16000;
y=wavrecord(1*fs,fs,1,'double');
if length(y)<1157
result=sim(net0,cat(1,y,zeros(1157-length(y),1)))
else
result=sim(net0,y)
end
end

Another query came to my mind:
Is it possible to load and use a neural network object file in "gui" local function?

Refer to the FAQ for several methods to share variables outside of their own local function, which is usually only where they are in scope. http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F
