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

Constructor from constraint.

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.

virtual void ClpConstraintLinear::deleteSome	(	int	numberToDelete,
		const int *	which
	)		[virtual]

Delete columns in constraint.

Implements ClpConstraint.

virtual void ClpConstraintLinear::reallyScale

(

const double *

columnScale

)

[virtual]

Scale constraint.

Implements ClpConstraint.

virtual int ClpConstraintLinear::markNonlinear

(

char *

which

)

const [virtual]

Given a zeroed array sets nonlinear columns to 1.

Returns number of nonlinear columns

Implements ClpConstraint.

virtual int ClpConstraintLinear::markNonzero

(

char *

which

)

const [virtual]

Given a zeroed array sets possible nonzero coefficients to 1.

Returns number of nonzeros

Implements ClpConstraint.
