If you try to implement this in maple, as I did, you really really develop desire to have a typed CAS at your finger tips, one of my motivations to use AXIOM on a more frequent basis. (I could provide ugly examples in maple where typing would prevent nonsense from being produced, ...) Even more discusting you need to produce in untyped languanges your types yourself, loosing tremendously working power for your actual subject.

(I don't want to see a list of lists etc of the components though) Enjoy AXIOM :)) Ciao BF. % PD Dr Bertfried Fauser % Institution: Max Planck Institute for Math, Leipzig <http://www.mis.mpg.de> % Privat Docent: University of Konstanz, Phys Dept <http://www.uni-konstanz.de> % contact|->URL : http://clifford.physik.uni-konstanz.de/~fauser/ % Phone : Leipzig +49 341 9959 735 Konstanz +49 7531 693491 _______________________________________________ Axiom-math mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/axiom-math
