%description
Sampling from the Cholesky factorization of a Wishart random variable,
sampling from the inverse Wishart distribution, sampling from the Cholesky
factorization of an inverse Wishart random variable, sampling from the
pseudo Wishart distribution, sampling from the generalized inverse Wishart
distribution, computing densities for the Wishart and inverse Wishart
distributions, and computing the multivariate gamma and digamma functions.
Provides a header file so the C functions can be called directly from
other programs.
