Block Diagonal Matrix
}
\description{
Build a block diagonal matrix.
}
\usage{
blkdiag(...)
}
\arguments{
\item{\dots}{sequence of non-empty, numeric matrices}
}
\details{
Generate a block diagonal matrix from A, B, C, ....
All the arguments must be numeric and non-empty matrices.
}
\value{
a numeric matrix
}
\note{
Vectors as input have to be converted to matrices before. Note that
\code{as.matrix(v)} with \code{v} a vector will generate a column vector;
use \code{matrix(v, nrow=1)} if a row vector is intended.

a1 <- matrix(c(1,2), 1)
a2 <- as.matrix(c(1,2))
blkdiag(a1, diag(1, 2, 2), a2)
