## Constructor & Destructor Documentation

ClpPackedMatrix2::ClpPackedMatrix2 | ( |  | ) |

Default constructor.

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

Constructor from copy.

virtual ClpPackedMatrix2::~ClpPackedMatrix2 | ( |  | ) | `[virtual]`

Destructor.

ClpPackedMatrix2::ClpPackedMatrix2 | ( | const ClpPackedMatrix2 & |  | ) |

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.
