```

this also works

Z=[0;0;0]; A = randn(3,1); B = randn(3,1); N = cross (A,B);
vrml_browse ([vrml_cyl([Z,A],"arrow","col",[1 0
0]),vrml_cyl([Z,B],"arrow","col",[0 1 0]),vrml_cyl([Z,N],"arrow")])

If you have octave-forge and freewrl (there's @ least a Debian
package).

Hth,

# Is it possible to plot vectors in 3D?

# I'm trying to visualise some 3D vectors, e.g.:
#
# A = [1;2;3]
# B = [5,4,6]
# AB = A - B
# N = cross(A, B)
#
# I'd like to put dots at points A and B, and then plot the vector AB with
# an arrow and the normal N with an arrow.
