Output not volume but surface using delaunayTriangulation

I would like to truangulate my data nodes.

This can be done by combination of delaunay and triangulation commands,

as demonstrated in the trisurf documentation, https://jp.mathworks.com/help/matlab/ref/trisurf.html

However, I have to ADD and DELETE the nodes and subsequently update the triangulation,

which is the key feature of the delaunaytriangulation command.

As known, delaunaytriangulation outputs tetrahedra connections for 3d data.

I would like to obtain the triangulation of the surface.

Now, I am lokking for any ideas.

Exactry the same question has been already given,

but this has been unsolved.

That kind of triangulation will never work for your kind of data.

I suggest that you use boundary() and adjust the alpha parameter.
