Surface triangulation of 3D points cloud

Hi everyone I was wondering if it is possible, starting from a Matrix A that describes, for each row, the coordinates of my points cloud, to create a surface mesh of my matrix A made by triangles. i tried with delaunay triangulation, but it seems that gives me a thetraedral mesh, insted i want to triangulate only the boundaries to create a .stl file. How could i do? Any help would be appreciated, Lorenzo

@Lorenzo Bennati, did this work for you? I am also trying to do this.
