Constructor & Destructor Documentation

AbcMatrix2::AbcMatrix2 ( )

Default constructor.

AbcMatrix2::AbcMatrix2 ( AbcSimplex model,
const CoinPackedMatrix rowCopy 

Constructor from copy.

AbcMatrix2::~AbcMatrix2 ( )


AbcMatrix2::AbcMatrix2 ( const AbcMatrix2 )

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

bool AbcMatrix2::usefulInfo ( ) const

Returns true if copy has useful information.
