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

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.

Syntax
C#

    public void ChgMCoef(
    	int ncoefs,
    	int[] rowind,
    	int[] colind,
    	double[] rowcoef
    )

#### Parameters

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