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

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.

Syntax
C# 
public void GetQRowQMatrixTriplets(
	int row,
	out int p_ncoefs,
	int[] rowqcol1,

	double[] rowqcoef
)

Parameters

row   Int32
Index of the row for which the quadratic coefficients are to be returned.
