DVSOLRun Method

public void Run(
	ref double[] WM,
	int offset_wm,
	int[] IWM,
	int offset_iwm,
	ref double[] X,
	int offset_x,
	ref int IERSL
)

Parameters

WM  Double

= Real work space containing the inverse diagonal matrix if MITER = 3 and the LU decomposition of the matrix otherwise. Storage of matrix elements starts at WM(3). WM also contains the following matrix-related data: WM(1) = SQRT(UROUND) (not used here), WM(2) = HRL1, the previous value of H*RL1, used if MITER = 3.

offset_wm  Int32

The starting offset in WM.

IWM  Int32

= Integer work space containing pivot information, starting at IWM(31), if MITER is 1, 2, 4, or 5. IWM also contains band parameters ML = IWM(1) and MU = IWM(2) if MITER is 4 or 5.

offset_iwm  Int32

The starting offset in IWM.

X  Double

= The right-hand side vector on input, and the solution vector on output, of length N.

offset_x  Int32

The starting offset in X.

IERSL  Int32

= Output flag. IERSL = 0 if no trouble occurred. IERSL = 1 if a singular matrix arose with MITER = 3.
