Hi everyone!
I have an easy question. I have the attached variable, and I usually reprent it as a 2D figure with the next code:
>> [X, h] = contourf(Pedobarography,'LevelList',[0.1:20000:150000]);
colormap('parula');
colorbar;
set(gca, 'YDir','reverse')
Now I want to show it as a 3D figure, I have tried with 'surf (Pedobarography)', but obtained figure is black
Any solution?
Thanks in advanced!

Black surf plots are common with very densely-gridded data.
To avoid that, set 'EdgeColor' to 'none':
D = load('Pedobarography.mat');
PB = D.Pedobarography;
figure
surf(PB, 'EdgeColor','none')
colormap('parula');
colorbar;
set(gca, 'YDir','reverse')
grid on
producing:
