## Constructor & Destructor Documentation

AbcMatrix2::AbcMatrix2 | ( |  | ) |

Default constructor.

AbcMatrix2::AbcMatrix2 | ( | AbcSimplex * | model,
|  | const CoinPackedMatrix * | rowCopy |
| ) |  |  |

## 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`[inline]`

Returns true if copy has useful information.

Definition at line 509 of file AbcMatrix.hpp.

AbcMatrix2& AbcMatrix2::operator= | ( | const AbcMatrix2 & |  | ) |

The copy constructor.
