Parameters

Y  Double

= The dependent variable, a vector of length N, input.

offset_y  Int32

The starting offset in Y.

YH  Double

= The Nordsieck (Taylor) array, LDYH by LMAX, input and output. On input, it contains predicted values.

offset_yh  Int32

The starting offset in YH.

LDYH  Int32

= A constant .ge. N, the first dimension of YH, input.

VSAV  Double

= Unused work array.

offset_vsav  Int32

The starting offset in VSAV.

SAVF  Double

= A work array of length N.

offset_savf  Int32

The starting offset in SAVF.

EWT  Double

= An error weight vector of length N, input.

offset_ewt  Int32

The starting offset in EWT.

ACOR  Double

= A work array of length N, used for the accumulated corrections to the predicted y vector.

offset_acor  Int32

The starting offset in ACOR.

IWM  Int32

Integer work space for the linear solver.

offset_iwm  Int32

The starting offset in IWM.

WM  Double

Real work space for the linear solver.

offset_wm  Int32

The starting offset in WM.

F  IFEX

= Dummy name for user supplied routine for f.

JAC  IJEX

= Dummy name for user supplied Jacobian routine.

PDUM  IFEX

= Unused dummy subroutine name. Included for uniformity over collection of integrators.

NFLAG  Int32

= Input/output flag, with values and meanings as follows: INPUT 0 first call for this time step. -1 convergence failure in previous call to DVNLSD. -2 error test failure in DVSTEP. OUTPUT 0 successful completion of nonlinear solver. -1 convergence failure or singular matrix. -2 unrecoverable error in matrix preprocessing (cannot occur here). -3 unrecoverable error in solution (cannot occur here).

RPAR  Double

User-defined real parameter array passed to callback routines.

offset_rpar  Int32

The starting offset in RPAR.

IPAR  Int32

User-defined integer parameter array passed to callback routines.

offset_ipar  Int32

The starting offset in IPAR.
