GetMQObj Method (Int64[], Int32[], Double[], Int64, Int64, 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: 44.01.01
Syntax
C# 
public void GetMQObj(
	long[] start,
	int[] colind,
	double[] objqcoef,
	long maxcoefs,
	out long p_ncoefs,
	int first,
	int last
)

Parameters

start
Type:  System.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
Type:  System.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
Type:  System.Double
Double array of length maxcoefs which will be filled with the nonzero element values. May be null if maxcoefs is 0.
maxcoefs
Type:  System.Int64
The maximum number of elements to be returned (size of the arrays).
p_ncoefs
Type:  System.Int64
Pointer to an integer where the number of nonzero quadratic objective coefficients will be returned. If the number of nonzero coefficients is greater than maxcoefs, then only maxcoefs elements will be returned. If p_ncoefs is smaller than maxcoefs, then only p_ncoefs will be returned. May be null.
first
Type:  System.Int32
First column in the range.
last
Type:  System.Int32
Last column in the range.
