flow {pomp} | R Documentation |
Compute the flow induced by a deterministic vectorfield or map.
## S4 method for signature 'pomp' flow(object, x0, t0, times, params, ..., verbose = getOption("verbose", FALSE))
object |
an object of class ‘pomp’, or of a class that extends ‘pomp’.
This will typically be the output of |
x0 |
an array with dimensions |
t0 |
the time at which the initial conditions are assumed to hold. |
times |
a numeric vector (length |
params |
a |
... |
Additional arguments are passed to the ODE integrator (if the skeleton is a vectorfield) and are ignored if it is a map.

In the case of a discrete-time system (map), flow
iterates the map to yield trajectories of the system.
In the case of a continuous-time system (vectorfield), flow
uses the numerical solvers in deSolve to integrate the vectorfield starting from given initial conditions.
flow
returns an array of dimensions nvar
x nrep
x ntimes
.
If x
is the returned matrix, x[i,j,k]
is the i-th component of the state vector at time times[k]
given parameters params[,j]
