pastvalue R Documentation
Retrieve Past Values (lags) During Gradient Calculation
Description
These routines provides access to variable history at lagged times.
The lagged time t must not be less than t0, nor should it be greater
than the current time of gradient calculation.
The routine cannot be directly called by a user, and will only work during the
integration process as triggered by the dde routine.
Usage
pastvalue(t)
pastgradient(t)
Arguments
t
Access history at time t.
Value
Vector of variable history at time t.
