Sets nonzero elements of the coefficient matrix of the invoking LP matrix.

Namespace: ILOG.Concert
Assembly: ILOG.CPLEX (in ILOG.CPLEX.dll) Version: 22.1.1.0

Syntax

C#
void SetNZs(
	int[] rowind,
	int[] colind,
	double[] val
)
Visual Basic
Sub SetNZs ( _
	rowind As Integer(), _
	colind As Integer(), _
	val As Double() _
)

Parameters

rowind
Type: array<System..::..Int32>[]()[][]
An array containing the row indices of the matrix coefficients to be set.
colind
Type: array<System..::..Int32>[]()[][]
An array containing the column indices of the matrix coefficients to be set.
val
Type: array<System..::..Double>[]()[][]
An array containing the values of the new matrix coefficients to be set.

Remarks

By doing this, you are implicitly changing the expressions of the range constraints corresponding to the row indices of the affected nonzero elements.
