Coloring Function for mesh

Hey,
In default, when you make a graph via mesh(), the colouring scheme is a gradient from cold to hot as the z-axis increases in value (as z increases, the colour gets warmer). Instead, I'd like the gradient to work as a function of a 2d distance (specifically, as x^2+y^2 increases, the colour should get colder). Is there a relatively simple way to do this? Thanks!

Sure:
L = membrane; %sample data
ax = mesh(L); %mesh it!
sz = size(L,1); %how big?
set(ax,'cdata',bsxfun(@hypot,(1:sz)',1:sz),'cdatamapping','scaled'); %what color?
colormap(flipud(jet)); %colder is bigger
