TransfoParam(ParamIn, Direction, FUN_TRANSFO)
}
\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}

\item{FUN_TRANSFO}{[function] model parameters transformation function (e.g. TransfoParam_GR4J, TransfoParam_CemaNeigeGR4J)}
}
\value{
\emph{ParamOut} [numeric] matrix of parameter sets (sets in line, parameter values in column)
}
\description{
Function which transforms model parameters using the provided function (from raw to transformed parameters and vice versa).
