how to use the pushbutton in GUI to record the voice

hello , I was trying to apply GUI with guide to my code voice recognition I actually dont know a lot about GUI .first, what I want to do is to assgin a push button for recording , how can I do that? I know how to make the figure but I dont know how to proceed after that starting from the option view callbacks ,here is a simple code as a start ,

rec1 = audiorecorder(22050, 16, 2);

disp('Start speaking.')

recordblocking(rec1, 2);

disp('End of Recording.');

any advice would be appreciated .

pushbuttonhandle = uicontrol('Style', 'Pushbutton', 'String', string, 'Position', [x, x, x, x], 'Callback', callback function);

@enas: "Didn't work" does not allow us to recognize, what is happening. Please spend the time to explain any details. Show us your code and explain the problems.

Try reading the getting started section of GUI's , and have a look in to these lines:

% Create the Audio recorder Object

>> rec = audiorecorder(22050, 16, 2);

% Create a Function to create the GUI

function test(rec)
  f= figure ;
  uicontrol(f,'style','pushbutton','position',[10 10 200 20],'String','Record','CallBack',@buttonCallback) ;
  function buttonCallback(~,~)
      disp('Recording... start talking');
      rec.recordblocking(2);
      disp('Stopped.');
  end
end

% Execute the function with the object as a parameter

 >> test(rec)

thanks that helped , do you know how to combine it with rest of my code ? I want the code be waiting for the pushbutton then continue excuting ,

[x1,fs]=wavread('C:\Users\user\Documents\MATLAB\red.wav');

X1=x1(:,1);

rec = audiorecorder(22050, 16, 2);

test(rec);

play(rec);

y= getaudiodata(rec);

Y=y(:,1);

z1=xcorr(X1,Y);

maxred=max(z1);

length1=length(z1);

t1=-((length1-1)/2):1:((length1-1)/2);

t1=t1';

max5=15; all=[maxred max5]

m=max(all);

if m<=maxred

    soundsc(wavread('red.wav'),22050)

disp('red');

        else soundsc(wavread('denied.wav'),8000)

disp('denied');

end
