Do you mean like this:
workspace
R = 2;
[x,y,z] = sphere;
% Define rows to keep as those with Z in the middle
topCap = z > .5;
bottomCap = z < -.5;
% Max out z at the cap values where x and y are in the cap.
z(topCap) = 0.5;
z(bottomCap) = -0.5;
% Display it.
surf(R*x, R*y, R*z);
axis equal

I don't think that's a MATLAB question. But if you get x, y, and z, by using for loops over phi and theta, then simply do what I did to clip the z values to some cap values:
% Max out z at the cap values where x and y are in the cap.
z(topCap) = 0.5;
z(bottomCap) = -0.5;
