\description{
  Methods for coercion from and to sparse matrices from package \pkg{SparseM}
  are provided here, for ease of porting functionality to the
  \pkg{Matrix} package, and comparing functionality of the two
  packages.  All these work via the usual \code{\link{as}(., "<class>")}
  coercion, \preformatted{  as(from, Class)
}%pre
}
