Dear Volker and all,
I support the change proposed by Volker.
I would also like to humbly ask for a few other matrix functions if you are working on this issue:
concatenation: (putting two matrices into one, e.g. A(2x2) B(2x2) and [A B] is 2x4.
creation: It would also be great if matrix( a,b,c,.. ) could work with matrix columns as well as with rows.
- a kind of concatenation this too...
Just my wish list, until I learn lisp to do it myself.
Thanks everybody for the great program Maxima,
G?ran
