help cform tells you
rgb = imread('peppers.png');
cform = makecform('srgb2lab');
lab = applycform(rgb, cform);

@zee falcon: what output do you expect? How are you checking it?

zee, you can also use rgb2lab(). But like Steven asked, what output are you expecting? You get an image. And do see that image you can use imshow(), or you can just look at it's values in the variable editor in the workspace. But no output will get "shown" unless you do one of those two things. Otherwise all you get is a new variable.
