I'm guessing that returning the object as you describe will create a lot of overhead in the processing time. I will check that out now....hopefully I'm wrong. Thanks again for your effort in explaining me the details Best Regards Thomas

OR make sure you call the filtering with a left-hand side (the updated object) and use that for the next step. -- Loren http://blogs.mathworks.com/loren http://matlabwiki.mathworks.com/MATLAB_FAQ

(even if your class never does anything graphical) classdef your_class < hgsetget see http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_oop/brfyl44-1.html for an explanation on what it does... us

I will get the latest Matlab version later today along with my new laptop. Should I then disregard this advice of yours and do something else? Thanks again for your kind and informative support!
