The code below plots a spherical helix.
What I want is another spherical helix plotted on top but rotated 90deg about the z axis (different colors are to be used for the second helix)
% Set the Order #
Order = 5;
% Set 3D attributes
t = 0:0.01:Order*pi;
% set x, y and z curves
%positive half
xp = sin(-t/Order).*cos(t);
yp = sin(t/Order).*sin(t);
zp = cos(t/Order);
%Negative Half
xn = sin(t/Order).*cos(t);
yn = sin(-t/Order).*sin(t);
zn = cos(t/Order);
% Set figure number
figure(Order);
% Plot all curves as defined
plot3(xp, yp, zp, xn, yn, zn);
% Label 3D axis
xlabel('X');
ylabel('Y');
zlabel('Z');
