\title{Transformation of the parameters from the GR4J model}
\usage{
TransfoParam_GR4J(ParamIn, Direction)
}
\arguments{
\item{ParamIn}{[numeric] matrix of parameter sets (sets in line, parameter values in column)}

\item{Direction}{[character] direction of the transformation: use "RT" for Real->Transformed and "TR" for Transformed->Real}
}
\value{
\emph{ParamOut} [numeric] matrix of parameter sets (sets in line, parameter values in column)
}
\description{
Function which transforms model parameters (from real to transformed parameters and vice versa).
}
\examples{
require(airGR)
