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

Returns the nonzeros in a quadratic constraint coefficients matrix as triplets (index pairs with coefficients). To achieve maximum efficiency, getQRowQMatrixTriplets returns the lower triangular part of this matrix only.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.01
Syntax
C# 
public int GetQRowQMatrixTriplets(
	int row,
	int[] rowqcol1,
