AddRows(Int32, Int32, Char[], Double[], Double[], Int32[], Int32[], Double[]) Method

Adds rows to the optimizer matrix.

Namespace:  Optimizer
Assembly: xprsdn (in xprsdn.dll) Version: 45.01.02+1f9fd7ff9a8620394fec1839699751312debed40
Syntax
C# 
public void AddRows(
	int nrows,
	int ncoefs,
	char[] rowtype,
	double[] rhs,
	double[] rng,
	int[] start,
	int[] colind,
	double[] rowcoef
)

Parameters

nrows   Int32
Number of new rows.
ncoefs   Int32
Number of new nonzeros in the added rows.
rowtype   Char
Character array of length nrows containing the row types:
  • L: indicates a <= row;
  • G: indicates >= row;
  • E: indicates an = row.
  • R: indicates a range constraint;
  • N: indicates a nonbinding constraint.
rhs   Double
Double array of length nrows containing the right hand side elements.
rng   Double
Double array of length nrows containing the row range elements. This may be null if there are no ranged constraints. The values in the rng array will only be read for R type rows. The entries for other type rows will be ignored. The lower bound on a range row is the right hand side value minus the range value. The sign of the range value is ignored - the absolute value is used in all cases.
start   Int32
Integer array of length nrows containing the offsets in the colind and rowcoef arrays of the start of the elements for each row.
colind   Int32
Integer array of length ncoefs containing the (contiguous) column indices for the elements in each row.
rowcoef   Double
Double array of length ncoefs containing the (contiguous) element values.
