theta =0:2*pi:100;
r=linspace(0,100,numel(theta)); % theta and r should have same length/ or either one be a scalar
z=2*(r-4*sin(theta)./r);

The variable r has just two elements: [0 100].
theta has 16 elements: [0 6.2832 12.5664 18.8496 ...]
What do you expect to happen when you try to divide a vector with 16 elements by one with 2 elements?
