Transition ODEs written in d/dt() format to matrix exponential / inductive linearization format

Usage

indLin(model, doConst = FALSE, calcSens = NULL)

rxOdeToIndLin(model, doConst = FALSE, calcSens = NULL)

rxToIndLin(model, doConst = FALSE, calcSens = NULL)

Arguments

model

rxode2 model, text, or function

doConst

Replace constants with values; By default this is FALSE.

calcSens

A character vector of parameter names for which sensitivities should be calculated.

Value

A character string representing the matrix exponential model code
