MATLAB: How to 3D plot function

3dplot

Hello, I'm trying to 3D plot the following function:
function f = spheresize(x)
f=((3*x(1)^2*x(2))/4*pi)^(1/3);
end
I'm very new to mathlab so I've been trying different ways of doing it (plot3, ezsurf, fsurf) but I always come up with some error… I know I have to feed it some vectors but I'm not really sure the correct way to do it and I haven't been able to get it by googling other examples.

  • fsurf(@(x,y)spheresize([x;y]), [-5 5 0 10])
    function f = spheresize(x)
    f=((3*x(1,:).^2.*x(2,:))/4*pi).^(1/3);
    end
