Try to use following code
function VideoDemo
global indx
global vHandle
vHandle=videoinput('winvideo');
start(vHandle);
indx=1;
showTimer=timer('timerFcn',@timefcn);
set(showTimer,'ExecutionMode','fixedRate','Period',5);
start(showTimer)
function timefcn(varargin)
global vHandle
imshow(getsnapshot(vHandle));
drawnow;
