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

Adds rows to the optimizer matrix.
Namespace: Optimizer
Assembly: xprsdn (in xprsdn.dll) Version: 46.01.02+e8d9493ad804415424ae931ce2abaeb6c55a6d5a
Syntax
C#

    public void AddRows(
    	int nrows,
    	int ncoefs,
    	char[] rowtype,
    	double[] rhs,
    	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.
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. 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.
