How do I construct a sphere with lines of latitude using loops and not the inbuilt sphere function in matlab

clearvars
R = 1;
xo = 10;
yo = 20;
zo = 30;
num_angles = 3600;
latitudes = -80:20:80; % latitudes in degrees
theta = linspace(0,2*pi,num_angles)';
% lat_angle = latitides*pi/180;
x = R * cosd(latitudes);
z = R * sind(latitudes);
X = cos(theta) * x + xo;
Y = sin(theta) * x + yo;
Z = repmat(z, size(X,1),1) + zo;
clf
plot3(X,Y,Z);
axis equal
