Hi,I have the element information of a mesh
but the mesh is too sparse. I extract all the faces of the mesh element and apply loop refinement for encryption
loop refinement extracts the midpoint of each face and generates a new triangle
but only generates a three-dimensional matrix
How do I merge the faces of a three-dimensional matrix into a new tetrahedron by index?

The process you've described doesn't uniquely determine what the new tetrahedron decomposition should be. However, you could use delaunayn on your augmented list of vertices (the original vertices plus the new ones) to generate one possible decomposition.
