TransfoParam_GR6J: Transformation of the parameters of the GR6J model

Description

Function which transforms model parameters of the GR6J model (from real to transformed parameters and vice versa).

Usage

TransfoParam_GR6J(ParamIn, Direction)

Arguments

ParamIn

[numeric] matrix of parameter sets (sets in line, parameter values in column)

Direction

[character] direction of the transformation: use "RT" for Raw -> Transformed and "TR" for Transformed -> Raw

Value

ParamOut [numeric] matrix of parameter sets (sets in line, parameter values in column)
