mvgamma

Multivariate Gamma function (of complex variable)

The multivariate Gamma function (mvgamma) and its logarithm (lmvgamma).

lmvgamma(x, p)

mvgamma(x, p)

`x`	a real or a complex number; `Re(x)>0` for `lmvgamma` and `x` must not be a negative integer for `mvgamma`
`p`	a positive integer, the dimension

A real or a complex number.

x <- 5
mvgamma(x, p = 2)
sqrt(pi)*gamma(x)*gamma(x-1/2)
