\title{Compute the variance, covariance matrix of K coordinate matrices.}
\usage{
mvar(...)
}
\arguments{
\item{...}{the set of matrices}
}
\description{
Covariance between two matrices is defined as the sum of the
sigular values of the X'Y matrix. All the matrices must have
the same number of rows.
}
\examples{
   # Build Three matrices of 3 rows.
   A <- matrix(1:9,nrow=3)
   B <- matrix(10:15,nrow=3)
   C <- matrix(20:31,nrow=3)
   # compute the variance covariance matrix
   mvar(A,B,C)
   mvar(A=A,B=B,C=C)
