Member Function Documentation

void AbcMatrix2::transposeTimes	(	const AbcSimplex *	model,
		const CoinPackedMatrix *	rowCopy,
		const CoinIndexedVector &	x,
		CoinIndexedVector &	spareArray,
		CoinIndexedVector &	z
	)		const

Return x * -1 * A in z.

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