pomp (version 0.53-1)

skeleton-pomp: Evaluate the deterministic skeleton at the given points in state space.

Description

The method skeleton computes the deterministic skeleton. In the case of a discrete-time system, this is the one-step map. In the case of a continuous-time system, this is the vector-field. NB: skeleton just evaluates the deterministic skeleton; it does not iterate or integrate. This function is part of the low-level interface to pomp objects. This help page does not give instructions on the implementation of models: see pomp for instructions.

Usage

## S3 method for class 'pomp':
skeleton(object, x, t, params, \dots)

Arguments

Value

  • Returns an array of dimensions nvar x nreps x ntimes. If f is the returned matrix, f[i,j,k] is the i-th component of the deterministic skeleton at time times[k] given the state x[,j,k] and parameters params[,j].

Details

This function makes repeated calls to the user-supplied skeleton of the pomp object. For specifications on supplying this, see pomp.

The function trajectory iterates the skeleton (in case it is a map) or integrates it using an ODE solver (in case it is a vectorfield).
