MATLAB: 3D surface plot

3d surface plot

Hello,

I have plot a 3d figure. But the height on the z-axis looks like a flat 2d surface.

How can I plot the height and makes the height displays like a 3d surface.

Many thanks!

It depends what your data are.

If you are currently using scatter3 or plot3, and your data are reasonably ordered, instead use surf.

If your data are random, create a surface using griddata (or similar functions) to interpolate your point data to a surface that surf can use.

Use griddata and meshgrid

A = rand(10,5,3);
A = sum(A);
A = squeeze(A);
surf(A,'LineWidth',2)
