Extract the Compartmental Operator
# S4 method for NlModel
getDecompOp(object)The actual class of the result can vary.
It will be a subclass of DecompOp.
These objects are an abstraction for a complete description of the fluxes in
the pool system regardless of the form it is provided in.
The information contained in these objects is equivalent to the set of internal and outward fluxes as
functions of pool contents and time and sufficient to infer
the "Compartmental Matrix" as a matrix valued function of the same arguments.
In the general case of a nonautonomous nonlinear Model this function
is a true function of both, the pool contents and time.
In the case of an non-autonomous linear model it is a function of time only,
and in case of a autonomous linear model it is a constant matrix.
The vector valued function can be inferred by the generic
function getFunctionDefinition.
A modelrun as produced by the constructors:
Model,
Model_by_PoolNames,
Model_14
the function GeneralModel or the functions listed in
predefinedModels.
A model represents the initial value problem (IVP)
for the contents of the pool consisting of
The initial values of the pool content
The system of ordinary differential equations, as dictated by the fluxes
The times for which the solution of the IVP is evaluated.
