MATLAB: Plotting sphere and rectangle mesh

meshrectanglesphere

need help on plotting something like this :

any idea ?

sphere(20)
axis square

You can get the coordinates x,y and z

[x,y,z]=sphere(20)

You can plot a sphere

surf(x,y,z)

Try something like the following (z must be a matrix):

for m = 1:10
        x(m) = m;
    for n = 1:10
        y(n) = n;
        z(m,n) = n+m;
    end
end
surf(x,y,z)

% plane z=x,
figure
hold on
fsurf(@(x,y) x)
% plane z = y
fsurf(@(x,y) y)
