Mesh Generation in MATLAB

Question

Is there any subroutine in MATLAB that takes a list of points and returns me a nice grid that I can use to show my colleagues, for example, this?

In fact, all I need is just a simple 2D mesh generator that takes a series of X, Y coordinates (which defines the boundary of the region) and returns me a list of elements that can display this region well. I can do the rest using the MATLAB command to interpolate the Z value.

Edit: I'm not interested in using MATLAB to create the above plot. I am interested in using the MATLAB library to get a list of elements, so when I create this element myself (not MATLAB itself, but in my own C # program), I can get this mesh surface.

PS: I know this is DistMesh , but I'm looking for something simpler - maybe something built right into MATLAB. And no, meshgrid is not grid generation.

If your surface is in the form z = f (x, y), you can use:

If your surface is concave, pay attention to the reconstruction of the surface on the same site.
