jand

Description

approximate Jacobian via numDeriv::jacobian

Usage

jand(pars, resfn = NULL, bdmsk = NULL, resbest = NULL, ndstep = 1e-07, ...)

Arguments

pars	a named numeric vector of parameters to the model
resfn	a function to compute a vector of residuals
bdmsk	Vector defining bounds and masks. Default is NULL
resbest	If supplied, a vector of the residuals at the parameters pars to save re-evaluation.
ndstep	A tolerance used to alter parameters to compute numerical approximations to derivatives. Default 1e-7.
...	Extra information needed to compute the residuals
