Fairly large, if you insist on avoiding numpy. However, if your inputs are small enough, it may not matter a whole lot. You may want to use Raymond Hettinger's Matfunc.py module to implement the inverse matrices (or preferably, reformulate the problem to use a solver instead of inverting matrices explicitly): http://users.rcn.com/python/download/python.htm -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
