You can do this with imadjust().
outpict = imadjust(inpict,stretchlim(inpict,0));
That will work for gray or RGB images of any standard image class. The output class will be inherited from the input. If the input is RGB, each channel will be scaled independently.
There are also less convenient ways to do it
outpict = im2uint8(mat2gray(inpict));
That will work for gray or RGB images of any class, but the output will always be uint8, regardless of the input class. If the input is RGB, the entire array will be scaled as a whole.
