In rxode2: Facilities for Simulating from ODE-Based Models

Differentiate and expand a matrix exponential model with forward sensitivities

Description

Differentiate and expand a matrix exponential model with forward sensitivities

Usage

rxSensMatExp(
  model,
  calcSens,
  calcSens2 = NULL,
  calcSens3 = NULL,
  doConst = FALSE,
  env = NULL
)

Arguments

model	rxode2 model, text, or function
calcSens	A character vector of parameter names for which sensitivities should be calculated.
calcSens2	character vector (or NULL) requesting second-order sensitivities ⁠rx__sens_<x>_BY_<p>_BY_<q>__⁠ (p over calcSens, q over calcSens2; every calcSens2 element must also be in calcSens). Expressed as k_from_to micro-constant transfers like the first-order ones. Ignored for linCmt() states (those use Stan forward-AD).
calcSens3	character vector (or NULL) requesting third-order sensitivities ⁠rx__sens_<x>_BY_<p>_BY_<q>_BY_<r>__⁠ (r over calcSens3). Requires calcSens2; every calcSens3 element must also be in calcSens2.
doConst	Replace constants with values; By default this is FALSE.
env	A pre-loaded symengine environment (from .rxLoadPrune()) to reuse instead of reloading model; when NULL it is built internally.

Value

A character string representing the matrix exponential sensitivity-expanded model code
