HYPERSPHERE_PROPERTIES
Properties of the M-dimensional Sphere


HYPERSPHERE_PROPERTIES is a C++ library which carries out various operations for an M-dimensional hypersphere, including converting between Cartesian and spherical coordinates, stereographic projection, sampling the surface of the sphere, and computing the surface area and volume.
