Contour plot on 3D in polar coordinates

Hello everyone:

I have a vector 'theta' that runs from 0 to 360 and have 180 items (theta = linspace(0,360,180)); and three vectors of dinstances d1,d2, d3 at r1 r2 and r3. I need to plot a polar contour plot of distances with this data.

thnx

What does "distance" mean in this context?

Are 3 vectors wich lengths are of 180 elements.

I'm going to assume "distance" maps to the height of an annular surface.

EDIT: I just realized you said 'contour' and not 'surf'. Added both

npoints = 10;
th = linspace(0,360,npoints);
r = [1; 2; 3].*ones(3,npoints);
d = rand(3,npoints); d(:,end) = d(:,1);

x = r.*cosd(th);
y = r.*sind(th);

subplot(2,1,1)
h = surf(x,y,d);
axis equal
shading interp
h.EdgeColor = [0 0 0];
subplot(2,1,2)
[~,h] = contourf(x,y,d);
axis equal

It worked TY!
