Description

Various utilities for the complex multivariate Gaussian distribution and complex Gaussian processes.

Index: This package was not yet installed at build time.

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.
