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.
