Description

Internal-use function which allows use of the PBSddesolv ODE solver. popModel

Usage

derivPBS(t, y, parms)

Arguments

t

Time step

y

state variables

parms

Additional parameters passed in from the original invoker of the solver

Details

note PBS does not allow lagged variables to be computed at the current timestep (hence the changes from the dede deriv function)

Value

the new model state.
