BasisStability Method (Int32, Int32, Int32, Double)

Calculates various measures for the stability of the current basis, including the basis condition number.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.01
Syntax
C# 
public void BasisStability(
	int type,
	int norm,
	int scaled,
	out double p_value
)

Parameters

type
Type:  System.Int32
  • 0: Condition number of the basis.
  • 1: Stability measure for the solution relative to the current basis.
  • 2: Stability measure for the duals relative to the current basis.
  • 3: Stability measure for the right hand side relative to the current basis.
  • 4: Stability measure for the basic part of the objective relative to the current basis.
norm
Type:  System.Int32
  • 0: Use the infinity norm.
  • 1: Use the 1 norm.
  • 2: Use the Euclidian norm for vectors, and the Frobenius norm for matrices.
scaled
Type:  System.Int32
If the stability values are to be calculated in the scaled, or the unscaled matrix.
p_value
Type:  System.Double
Pointer to a double, where the calculated value is to be returned.
