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.## S3 method for class 'pomp':
skeleton(object, x, t, params, \dots)pomp.x are nvars x nreps x ntimes, where nvars is the x.
Note that the x and params must agree in the number of their columns.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].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).
