I am attempting a quiver plot of symbolic functions starting with the
following example from MatLab. It appears the substitution gets hung up
some reason.
syms x y
u = sin(x^2 + y^2);
v = cos(x*y);
[X, Y] = meshgrid(-1:.1:1,-1:.1:1);
U = subs(u, [x y], {X,Y});
V = subs(v, [x y], {X,Y});
quiver(X, Y, U, V)
I get the following error messages:

wanted?)
