ClpPackedMatrix3::ClpPackedMatrix3 ( )

Default constructor.

ClpPackedMatrix3::ClpPackedMatrix3	(	ClpSimplex *	model,
		const CoinPackedMatrix *	columnCopy
	)

Constructor from copy.

virtual ClpPackedMatrix3::~ClpPackedMatrix3 ( ) [virtual]

Destructor.

ClpPackedMatrix3::ClpPackedMatrix3 ( const ClpPackedMatrix3 & )

The copy constructor.

void ClpPackedMatrix3::transposeTimes	(	const ClpSimplex *	model,
		const double *	pi,
		CoinIndexedVector *	output
	)			const

Return x * -1 * A in z.

Note - x packed and z will be packed mode Squashes small elements and knows about ClpSimplex
