GetMQObj(Int64[], Int32[], Double[], Int64, Int32, Int32) Method

Returns the nonzeros in the quadratic objective coefficients matrix for the columns in a given range. To achieve maximum efficiency, getMQObj returns the lower triangular part of this matrix only.

Namespace:  Optimizer
Assembly: xprsdn (in xprsdn.dll) Version: 45.01.02+1f9fd7ff9a8620394fec1839699751312debed40
Syntax
C# 
public long GetMQObj(
	long[] start,
	int[] colind,
	double[] objqcoef,
	long maxcoefs,
	int first,
	int last
)

Parameters

start   Int64
Integer array which will be filled with indices indicating the starting offsets in the colind and objqcoef arrays for each requested column. It must be length of at least last-first+2. Column i starts at position start[i] in the colind and objqcoef arrays, and has start[i+1]-start[i] elements in it. May be null if maxcoefs is 0.
colind   Int32
Integer array of length maxcoefs which will be filled with the column indices of the nonzero elements in the lower triangular part of Q. May be null if maxcoefs is 0.
objqcoef   Double
Double array of length maxcoefs which will be filled with the nonzero element values. May be null if maxcoefs is 0.
maxcoefs   Int64
The maximum number of elements to be returned (size of the arrays).
first   Int32
First column in the range.
last   Int32
Last column in the range.

Return Value

Int64
