Description

cmvnorm

Details

The DESCRIPTION file: cmvnorm cmvnorm

Generalizing the real multivariate Gaussian distribution to the complex case is not straightforward but one common approach is to replace the real symmetric variance matrix with a Hermitian positive-definite matrix. The cmvnorm package provides some functionality for the resulting density function.
