If I have a 1D vector in space(radius) and concentration for example, is there a simple way to create a meshplot with a circular simmetry? as if the plot has been rotated around the (0,0) and the concentration is displayed with colors (as in surf)
like from the image on the left to the image on the right (sorry I am bad at drawing)

% The grid:
x = linspace(-3, 3, 50);
y = linspace(-3, 3, 50);
R = sqrt(x.^2 + (y.').^2);
% The concentration:
Cx = linspace(0, 3, 100);
Cy = zeros(size(Cx));
Cy(1:50) = 3;
Cy(51:90) = linspace(3, 0, 40);
% The value:
z = interp1(Cx, Cy, R);
mesh(x, y, z)
imagesc(z)
