Hello, I would like to rotate B around the z axis and plot the contour plot. I tried the following but I don't think it is working since the contour plot after the rotation should not be symmetric.
Hope anyone can help,
thet=[0:0.01*pi:pi];
plane=[-15:0.02:15,15:0.02:15];
z = 10;
[theta,plane,z]=meshgrid(thet,plane,z);
[x,y,z]=pol2cart(theta,plane,z);
r = sqrt(x.^2+y.^2+z.^2)*1e-9;
B = const*((300e-18)./r.^5-1./r.^3)*1e6;
phi = 53;
%rotation around Z axis
X = x.*cos(phi) - y.*sin(phi);
Y = x.*sin(phi) + y.*cos(phi);
contourf(x,y,B,25,'LineStyle','none')

You aren't plotting the updated values X and Y. Last line should be:-
>> contourf(X,Y,B,25,'LineStyle','none')

I get exactly the same plot when I use contourf(X,Y,B,25) that's why I think it's not working.
