# How to plot surface with contour form vertices?

I got the vertices for my 3D surface and its value that need to be contoured.
I wonder how to do a surface plot with contour?
I found a simple way to do it with a scatter plot, but I don't know how to implement the code to be surface.
x = data(:,1);
y = data(:,2);
z = data(:,3);
d = data(:,4);
marker_size = 10;
scatter3(x,y,z,marker_size,d,'filled');

Unfortunately, it didn't work in this case since there are multiple z value in single x and y coordinate.

try to combine this
with this
%%structured
xi = unique(x) ; yi = unique(y) ;
[X,Y] = meshgrid(xi,yi) ;
Z = reshape(z,size(X)) ;
figure
surf(X,Y,Z)
%%unstructured
dt = delaunayTriangulation(x,y) ;
tri = dt.ConnectivityList ;
figure
trisurf(tri,x,y,z)
