case class NormalVec(mu: VectoD, cov: MatrixD, stream: Int = 0) extends VariateVec with Product with Serializable
The NormalVec class generates Normal (Gaussian) random variate vectors according
to the Multivariate Normal distribution with mean 'mu' and covariance 'cov'.
This continuous RVV models normally distributed multidimensional data.
- mu
the mean vector
- cov
the covariance matrix
- stream
the random number stream
