MATLAB is a general purpose programming language. You can compute with it nearly anything that is deterministically computable (provided you can fit it in memory.)

There is no specific MATLAB routine for the purpose you are looking for. There are a lot of different "features" that one might want to classify images on, and there are a lot of different classification routines.

If you could be more specific about how you want to do the classification, then someone might be able to suggest some existing routines that might help.

NASA's Goddard Space Flight Center (which someone at JPL told me has the largest collection of image processing people in the world) has recently released its Recursive Hierarchical Image Segmentation (RHSEG) package. It is not subject to patent restrictions and is released to the public through NASA's GSFC Open Source Release process. Check it out at NASA's web site: http://opensource.gsfc.nasa.gov/projects/HSEG/index.php Maybe some routines could be translated into MATLAB.
