Constructor & Destructor Documentation

ClpPackedMatrix2::ClpPackedMatrix2 ( )

Default constructor.

ClpPackedMatrix2::ClpPackedMatrix2 ( ClpSimplex model,
const CoinPackedMatrix rowCopy 

Constructor from copy.

virtual ClpPackedMatrix2::~ClpPackedMatrix2 ( )


ClpPackedMatrix2::ClpPackedMatrix2 ( const ClpPackedMatrix2 )

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

Returns true if copy has useful information.
