AddRows(Int32, Int64, Char[], Double[], Int64[], Int32[], Double[]) Method

Adds rows to the optimizer matrix.

Namespace:  Optimizer
Assembly: xprsdn (in xprsdn.dll) Version: 46.01.01+a3a330cd064168136e2506c7bff46e7bb9a4854d
Syntax
C# 
public void AddRows(
	int nrows,
	long ncoefs,
	char[] rowtype,
	double[] rhs,
	long[] start,
	int[] colind,
	double[] rowcoef
)

Parameters

nrows   Int32
Number of new rows.
ncoefs   Int64
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.
start   Int64
Integer array of length nrows containing the offsets in the colind and rowcoef arrays of the start of the elements for each row. May be null if none of the rows contain nonzero coefficients.
colind   Int32
Integer array of length ncoefs containing the (contiguous) column indices for the elements in each row. May be null if none of the rows contain nonzero coefficients.
rowcoef   Double
Double array of length ncoefs containing the (contiguous) element values. May be null if none of the rows contain nonzero coefficients.
