hello
see my demo below. Change the profile and data scaling accorsing to your needs
hope it helps
figure(3) plot :
code :
%% create the mexican hat 3D plot
% 2D line (profile along a radius)
r = linspace(0,1,100); % radius
zs = exp(-r.^2*16); % profile (along a radius)
figure(1);
plot(r,zs);
% create the 3D plot
theta = linspace(0,2*pi,length(r));
[x,y]=pol2cart(theta, r'); % NB the transposed r to create x, y as matrices and not just vectors !!
zsr=zs'*ones(1,length(r));
figure(2);
s = surf(x,y,zsr);
s.EdgeColor = 'none';
view([0 90]);
axis('equal');
% colormap('gray');
colormap('hot');
colorbar('vert');
% interpolation on a 1024 x 1024 square grid
ll = max(r) / sqrt(2);
m = linspace(-ll,ll,1024);
[Xq,Yq] = meshgrid(m,m);
zq = griddata(x,y,zsr,Xq,Yq);
figure(3);
s = surf(Xq,Yq,zq);
s.EdgeColor = 'none';
view([0 90]);
axis('equal');
% colormap('gray');
colormap('hot');
colorbar('vert');
xlim([-ll ll]);
ylim([-ll ll]);
