ChgMCoef Method (Int64, Int32[], Int32[], Double[])

Used to change multiple coefficients in the matrix. If any coefficient does not already exist, it will be added to the matrix. If many coefficients are being added to a row of the matrix, it may be more efficient to delete the old row of the matrix and add a new one.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 44.01.01
Syntax
C# 
public void ChgMCoef(
	long ncoefs,
	int[] rowind,
	int[] colind,
	double[] rowcoef
)

Parameters

ncoefs
Type:  System.Int64
Number of new coefficients.
rowind
Type:  System.Int32
Integer array of length ncoefs containing the row indices of the coefficients to be changed.
colind
Type:  System.Int32
Integer array of length ncoefs containing the column indices of the coefficients to be changed.
rowcoef
Type:  System.Double
Double array of length ncoefs containing the new coefficient values. If an element of rowcoef is zero, the coefficient will be deleted.
