I used ezsurf() to generate a 3D surface of 3 parameterized equations. I'd like to export the data as an stl file, but surf2stl() does not seem to working, any suggestions?

For reference, here is the code used to generate the 3D surface.

syms u v
x = (-2/15)*cos(u)* (3*cos(v) - 30*sin(u) + 90*(cos(u))^4*sin(u) - 60*(cos(u))^6*sin(u) + 5*cos(u)*cos(v)*sin(u))
y = (-1/15)*sin(u)* (3*cos(v) - 3*(cos(u))^2*cos(v) + 48*(cos(u))^4*cos(v) - 48*(cos(u))^6*cos(v) - 60*sin(u) + 5*cos(u)*cos(v)*sin(u) - 5*(cos(u))^3*cos(v)*sin(u) - 80*(cos(u))^5*cos(v)*sin(u) + 80*(cos(u))^7*cos(v)*sin(u))
z = (2/15)*(3+5*cos(u)*sin(u))*sin(v)
figure(2)
ezsurf(x,y,z,[0, pi, 0, 2*pi])

X = h.XData ; 
Y = h.YData ; 
Z = h.ZData ;
