stla_to_tri_surface_fast, a MATLAB code which is a "fast" version of STLA_TO_TRI_SURFACE.
STLA_TO_TRI_SURFACE_FAST reads data from an ASCII STLA file describing a triangular mesh of a 3D surface, and converts it to a pair of arrays describing a triangular mesh or TRI_SURFACE.
An ASCII STL file contains a description of the surface of a solid that has been decomposed into triangles. The vertices of the triangles should be listed in counterclockwise order, as viewed from outside the surface. A normal vector for the triangle may also be listed.
A TRI_SURFACE or triangulated mesh surface, is described by a pair of arrays:

stla_to_tri_surface_fast is available in a MATLAB version.
