Figure5-7

>> Y = sqrt(1 - Z.ˆ2).*sin(theta);
>> surf(X, Y, Z); axis square

The result is shown in Figure 5-7.

WiththeSymbolicMathToolbox,parametricplottingofsurfaceshas
been greatly simplified withthe commands ezsurf and ezmesh , and you can
obtain a result very similar to Figure 5-7 with

>> ezsurf('sqrt(1-sˆ2)*cos(t)', 'sqrt(1-sˆ2)*sin(t)', ...
's', [-1, 1, 0, 2*pi]); axis equal

Special Effects

So far we have only discussed graphics commands that produce or modify a
single static figure window. But MATLAB is also capable of combining several
