There is an entropyfilt() function in the Image Processing Toolbox.

entropyfilt() gives you the entropy at each location. This does not necessarily increase contrast. In fact it might not look much like a contrast adjusted version of the original at all. It looks more like an edge detection image. To increase contrast of an image, you should use imadjust().
