I am trying to plot a 3D figure defined by z>=0:

I triY(I),Z(I),'.'); xlabel('X'); ylabel('Y'); zlabel('Z');

Please help me

x = linspace(-2,2,50); 
y = linspace(-2,2,50);
z = linspace(-0.1,2,50);
x = reshape(x,[],1,1);
y = reshape(y,1,[],1);
z = reshape(z,1,1,[]);
R2 = x.^2+y.^2+z.^2;
I = R2>=1 & R2<=4 & z>=0;

isosurface(x,y,z,I,0.5); % 0.5 is middle of 0 and 1
axis equal

Is there a way that we can check the inner half of sphere (with radius 1)?

Use the mouse turn the object and look from bottom
