HYPERSPHERE_PROPERTIES is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
GEOMETRY, a MATLAB library which performs geometric calculations in 2, 3 and M dimensional space.
HYPERSPHERE_MONTE_CARLO, a MATLAB library which applies a Monte Carlo method to estimate the integral of a function on the surface of the unit sphere in M dimensions;
HYPERSPHERE_SURFACE, a MATLAB library which illustrates a procedure for estimating the location of a hypersurface defined by a characteristic function or a signed function.
RANDOM_DATA, a MATLAB library which generates sample points for various probability distributions, spatial dimensions, and geometries, including the M-dimensional cube, ellipsoid, simplex and sphere.
SPHERE_STEREOGRAPH, a MATLAB library which computes the stereographic mapping between points on the unit sphere and points on the plane Z = 1; a generalized mapping is also available
SPHERE_STEREOGRAPH_DISPLAY, a MATLAB library which computes and displays the results of several stereographic projections between a sphere and a plane.
