checkDLL | R Documentation |
Check shared library (DLL/.so) of a compiled model and create a list of symbols.
checkDLL(func, jacfunc, dllname, initfunc, verbose, nout, outnames, JT = 1)
func |
character: name of the derivative function. |
jacfunc |
an R function, that computes the
Jacobian of the system of differential equations
|
dllname |
a string giving the name of the shared library
(without extension) that contains all the compiled function or
subroutine definitions refered to in |
initfunc |
the name of the initialisation function
(which initialises values of parameters), as provided in
‘dllname’. See package vignette |
verbose |
reserved for future extensions. |
nout |
only used if |
outnames |
only used if ‘dllname’ is specified and
|
JT |
integer specifying the type of the Jacobian. The default value of 1
must be set to 2 for solver |
The function checkDLL
is normally called internally by the solver
functions. It can be used to avoid overhead, when a small compiled
model with a low number of integration steps is repeatedly called.
The feature is currently only available for the lsoda
solver.
List of class deSolve.symbols
with:
ModelInit |
pointer to the init function of the DLL (class "externalptr"). |
Func |
pointer to the derivative function in the DLL (class "externalptr"). |
JacFunc |
pointer to the Jacobi function in the DLL (class "externalptr"). |
Nglobal |
number of output variables calculated in the compiled function. |
Nmtot |
list of names of derivatives and output variables. |
