Re: [Maxima] Maxima + vector math



hi judah

you must rewrite at /usr/local/lib/maxima5.6/
share/vect.dem Line 5,LOAD("VECT.mc") to
LOAD("vect.mc").
Then run maxima.
(C1)load(vect);
(C2)express1([a,b,c]~[d,e,f]);
(D2) [bf-ce,cd-af,ae-bd]

more please read share/vect.mc especially
function express1.
