Syntax

C#
void SetNZ(
	int rowind,
	int colind,
	double val

Visual Basic
Sub SetNZ ( _
	rowind As Integer, _
	colind As Integer, _
	val As Double _
)

Parameters

rowind
Type: System..::..Int32
The row index of the matrix coefficient to be set.
colind
Type: System..::..Int32
The column index of the matrix coefficient to be set.
val
Type: System..::..Double
The value of the matrix coefficient to be set.

Remarks

By doing this, you are implicitly changing the expression of the range constraint corresponding to the row index of the affected nonzero element.
