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

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: 41.01.03
Syntax
C# 
public int GetMQObj(
	int[] start,
	int[] colind,
	double[] objqcoef,
	int maxcoefs,
	int first,
	int last
)

Parameters

start
Type:  SystemInt32
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 mrwind and dmatval arrays, and has start[i+1]-start[i] elements in it. May be null if maxcoefs is 0.
colind
Type:  SystemInt32
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
Type:  SystemDouble
Double array of length maxcoefs which will be filled with the nonzero element values. May be null if maxcoefs is 0.
maxcoefs
Type:  SystemInt32
The maximum number of elements to be returned (size of the arrays).
first
Type:  SystemInt32
First column in the range.
last
Type:  SystemInt32
Last column in the range.

Return Value

Type:  Int32
