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 Raw->Transformed and "TR" for Transformed->Raw}

}
\description{
Function which transforms model parameters of the GR4J model (from real to transformed parameters and vice versa).
