hello group,
I miss the function norm(u,2) and angle(u,v) to compute the length of a vector resp. the
angle between two vectors.
Ok, I have written those functions for myself in a straigt forward manner (vectors
represented als lists e.g. u: [1,2,3]) e.g. norm(u):= sqrt(u.u) resp. angle(u,v):=
(u.v)/(norm(u)*norm(v)) - and I'm quite happy with them, being not sure wether these
definitions are general enough ..
So I wonder if I have overlooked norm() and angle() (alias names?), because these
function
are standard functions in other CAS :)
