Density function and random generation from the Wishart distribution.
Positive definite matrix W (p x p).
Degrees of freedom (scalar).
Inverse scale matrix (p x p).
The mean of a Wishart random variable with
v degrees of freedom
and inverse scale matrix
S is vS.
dwish evaluates the density at positive definite matrix W.
rwish generates one random draw from the distribution.
