Constructor & Destructor Documentation

Default constructor.

ClpPackedMatrix2::ClpPackedMatrix2 ( ClpSimplex model,
const CoinPackedMatrix *  rowCopy 
)

Constructor from copy.

virtual ClpPackedMatrix2::~ClpPackedMatrix2 ( ) [virtual]

Destructor.

The copy constructor.


Member Function Documentation

void ClpPackedMatrix2::transposeTimes ( const ClpSimplex 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 ClpSimplex

bool ClpPackedMatrix2::usefulInfo ( ) const [inline]

Returns true if copy has useful information.
