pathmat |
matrix where the LNA path should be stored |
draws |
matrix of N(0,1) draws to be mapped to an LNA path |
lna_times |
vector of interval endpoint times |
lna_pars |
numeric matrix of parameters, constants, and time-varying covariates at each of the lna_times |
init_start |
index in the parameter vector where the initial compartment volumes start |
param_update_inds |
logical vector indicating at which of the times the LNA parameters need to be updated. |
stoich_matrix |
stoichiometry matrix giving the changes to compartments from each reaction |
forcing_inds |
logical vector of indicating at which times in the time-varying covariance matrix a forcing is applied. |
svd_d |
vector in which to store SVD singular values |
svd_U |
matrix in which to store the U matrix of the SVD |
svd_V |
matrix in which to store the V matrix of the SVD |
step_size |
initial step size for the ODE solver (adapted internally, but too large of an initial step can lead to failure in stiff systems). |
lna_pointer |
external pointer to LNA integration function. |
set_pars_pointer |
external pointer to the function for setting the LNA parameters. |
forcing_matrix |
matrix containing the forcings. |
fill out pathmat with the LNA path corresponding to the stochastic perturbations.
