    Syntax

    TF = isSelfIntersecting(mesh)

    Define mesh vertices and faces for the mesh.

    vertices =[0 0 0; 0 1 0; 1 0 0; 1 1 0; ...
            0.5 0.5 -1; 0 1 1; 1 0 1];
faces = [1 2 3; 2 3 4; 5 6 7];

    Create and display the surface mesh.

    mesh = surfaceMesh(vertices,faces);
surfaceMeshShow(mesh,Title="Input Mesh")

    Check if the mesh is self-intersecting.

    TF = isSelfIntersecting(mesh)
    TF = logical
   1
