rkInternal {deSolve} | R Documentation |
These are the internal workhorses of rk
,
which are normally not intended to be called by the end user.
Though internal, both functions are visible in the user's workspace to allow for easy inspection and fine-tuning of the algorithms by experienced users.
rkFixed(y, times, func, parms, tcrit = NULL, verbose = FALSE, hini = 0, method = rkMethod("rk4", ...), ...) rkAuto(y, times, func, parms, rtol = 1e-06, atol = 1e-06, tcrit = NULL, verbose = FALSE, hmin = 0, hmax = NULL, hini = 0, method = rkMethod("rk45dp7", ...), maxsteps = 5000, ...)
Arguments and value are described in the manual page of the top-level
function rk
. Note that rkFixed
is used for methods
with fixed time step and rkAuto
for embedded methods with
automatic step size determination. Both functions return raw values of
the integration without external interpolation and without the "global"
return values of the model.
