## Detailed Description

Definition at line 500 of file ClpPackedMatrix.hpp.

## 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.

Definition at line 514 of file ClpPackedMatrix.hpp.

ClpPackedMatrix2& ClpPackedMatrix2::operator= | ( | const ClpPackedMatrix2 & |  | ) |

The copy constructor.
