How to add 3D points to a surfc surface plot?

Hi MATLAB Central,

I have a 2D matrix called "HS" with columns (X) and rows (Y). Using the command below I can produce a beautiful 3D surface plot:

figure;
surfc(X, Y, HS);
shading interp

However, what I really want to do is to add points to the surface plot. So I want to do something like:

figure;
hold on;
surfc(X, Y, HS);
shading interp
plot3(x,y,z, 'ko');
hold off;

When I do this the 3D surface plot breaks down. Even in the absence of the plot3 command, just adding the hold on;/hold off; causes the surface plot to break down into a 2D heatmap.

Surely, there must be a way to co-plot points onto a 3D surface plot? Does anyone know how?

Thanks in advance,

Anders

More the "hold on" until after the "surfc".
