This one. What I need to know are the values for
points1 and vect1, after the execution of the four following sentences.
I don't see the error message you reported, so we need to isolate the
origin of the problem.
> a: {5,10,15,20};
> vf(x,y,z):= vector([x,y,z],2*[sin(x),cos(y),log(z)]);
> points1: cartesian_product(a,a,a);
> vect1: makeset(vf(x,y,z), [x,y,z], points1);
