SPHERETRI performs a triangulation of a unit sphere based on Icosahedron face partitioning

SPHERETRI is a set of high-performance vectorized MATLAB functions for building a triangulation of a unit sphere based on recursive partitioning of each of Icosahedron faces. The resulting triangulation vertices form a nearly even grid on a surface of a sphere.
