3d - How do I make a surf plot in MATLAB with irregularly spaced data? -

I know that I can create a 3D surface plot in MATLAB:

  x = Linspace (1,10,100); Y = Lynxpace (10,20,100); [X y] = meshgrid (x, y); Z = X * Y; Surf (x, y, z);  

But it requires that all the nodes for the line prepare the line. I have a set of data that has arbitrary digits (x, y) and height (z). Is there an easy way to plot a graph, which is the surf ?

You trisurf You can use the function:

  tri = delaunay (x, y); Trisurf (tri, x, y, z);  

If you have dense data then you want to check out the shading archive (or other values, check the Doctor Shading Get black blocks due to the grid).
