I dont know whether the the entropyfilt is included, but virtually all of the code used in DIPUM is available for download from the publishers site. Its URL is documented in the book. If you can't find it maybe Steve Eddins (One of the authors of the book, who often lurks around here;-) might come back and put you right as to where you can find it. Regards Dave Robinson

It is part of the Image Processing Toolbox, which is a commercial Matlab package. Either you do not have the Image Processing Toolbox or you have an older version and you will need to upgrade. If you do need to upgrade the IPT you will need to upgrade Matlab to match. entropyfilt was added in IPT 5.0 which was a number of releases ago (2005?) http://blogs.mathworks.com/steve/2009/07/30/five-years-of-image-processing-toolbox-changes/
