Syntax
C#

    public void ChgMQObj(
    	int ncoefs,
    	int[] objqcol1,
    	int[] objqcol2,
    	double[] objqcoef
    )

#### Parameters

ncoefs Int32
  The number of coefficients to change.
objqcol1 Int32
  Integer array of size ncoefs containing the column index of the first variable in each quadratic term.
objqcol2 Int32
  Integer array of size ncoefs containing the column index of the second variable in each quadratic term.
objqcoef Double
  New values for the coefficients. If an entry in objqcoef is 0, the corresponding entry will be deleted. These are the coefficients of the quadratic Hessian matrix.
