I saw a java library for image processing (or ND-tensor processing, rather) where they are doing just that. Each data point is wrapped in a "type", and operations occur at the level of types (so different types know how to deal with each other): http://pacific.mpi-cbg.de/cgi-bin/gitweb.cgi?p=imglib.git (There's a tiny tutorial on basics here: http://pacific.mpi-cbg.de/Imglib ) Albert -- http://albert.rierol.net -- You received this message because you are subscribed to the Google Groups "Clojure" group.
