vMF samples from von Mises-Fisher distribution and performs some operations. Unlike the movMF package, vMF does not consider mixtures of von Mises-Fisher distribution. vFM particularly focuses on sampling from the distribution and performs it very quickly. This is useful to carry out fast simulations in directional statistics. vMF also computes the density and normalization constant of the von Mises-Fisher distribution.
