GetLastBarSol Method (Double[], Double[], Double[], Double[], Int32)

Used to obtain the last barrier solution values following optimization that used the barrier solver.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.04
Syntax
C# 
public void GetLastBarSol(
	double[] x,
	double[] slack,
	double[] duals,
	double[] djs,
	out int p_status
)

Parameters

x
Type:  System.Double
Double array of length ORIGINALCOLS where the values of the primal variables will be returned. May be null if not required.
slack
Type:  System.Double
Double array of length ORIGINALROWS where the values of the slack variables will be returned. May be null if not required.
duals
Type:  System.Double
Double array of length ORIGINALROWS where the values of the dual variables ( cBTB-1) will be returned. May be null if not required.
djs
Type:  System.Double
Double array of length ORIGINALCOLS where the reduced cost for each variable ( cT-cBTB-1A) will be returned. May be null if not required.
p_status
Type:  System.Int32
Status of the last barrier solve. Value matches that of XPRS_LPSTATUS should the solve have been stopped immediately after the barrier.
