when i write a code in matlab, it shows my camera's default as YUY2 format instead of rgb format. This is troubling me a lot. How can i change it to rgb?...... I am also unable to save image. and import image from stored location on my laptop

Please see http://www.mathworks.com/matlabcentral/fileexchange/26249-yuy2-to-rgb-converter -- and be sure to read the description there, as it reports an alternate approach that might happen to work for you.

Use ReturnedColorSpace function to retain your camera to RGB format
You can use it in following way
myCam = imaq.VideoDevice('winvideo');
myCam.VideoFormat = 'YUY2_640x480';
myCam.ReturnedColorSpace = 'rgb';
vidPlayer = vision.DeployableVideoPlayer;
for idx = 1: 100
videoFrame = step(myCam);
step(vidPlayer,videoFrame);
end
release(myCam);
release(vidPlayer);
