		int	numberCoefficients,
		int	numberColumns,
		const int *	column,
		const double *	element

Member Function Documentation

virtual int ClpConstraintLinear::gradient	(	const ClpSimplex *	model,
		const double *	solution,
		double *	gradient,
		double &	functionValue,
		double &	offset,
		bool	useScaling = `false`,
		bool	refresh = `true`
	)			const `[virtual]`

Fills gradient.

If Linear then solution may be NULL, also returns true value of function and offset so we can use x not deltaX in constraint If refresh is false then uses last solution Uses model for scaling Returns non-zero if gradient udefined at current solution

Implements ClpConstraint.

virtual void ClpConstraintLinear::resize ( int newNumberColumns ) [virtual]

Resize constraint.

Implements ClpConstraint.
