MATLAB does not include any routines to do this. You will need to write your own (or find one of the many many people who have implemented the same assignment.)

I already posted code for that in this thread: http://www.mathworks.com/matlabcentral/answers/22329-lsb-code

It will be extremely straightforward to modify it to read in any type of image file formats you want.
