## Constructor & Destructor Documentation

ClpCholeskyUfl::ClpCholeskyUfl | ( | int | denseThreshold = `-1` | ) |

Constructor which has dense columns activated.

Default is off.

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

Destructor.

ClpCholeskyUfl::ClpCholeskyUfl | ( | const ClpCholeskyUfl & |  | ) | `[private]`

## Member Function Documentation

virtual int ClpCholeskyUfl::order | ( | ClpInterior * | model | ) | `[virtual]`

Orders rows and saves pointer to matrix.and model.

Returns non-zero if not enough memory

Reimplemented from ClpCholeskyBase.

virtual int ClpCholeskyUfl::symbolic | ( |  | ) | `[virtual]`

Does Symbolic factorization given permutation using CHOLMOD (if available).

This is called immediately after order. If user provides this then user must provide factorize and solve. Otherwise the default factorization is used returns non-zero if not enough memory.

Reimplemented from ClpCholeskyBase.

virtual int ClpCholeskyUfl::factorize | ( | const double * | diagonal,
|  | int * | rowsDropped |
| ) |  |  | `[virtual]`

Factorize - filling in rowsDropped and returning number dropped using CHOLMOD (if available).

If return code negative then out of memory

Reimplemented from ClpCholeskyBase.

virtual void ClpCholeskyUfl::solve | ( | double * | region | ) | `[virtual]`

Uses factorization to solve.

Uses CHOLMOD (if available).

Reimplemented from ClpCholeskyBase.

virtual ClpCholeskyBase* ClpCholeskyUfl::clone | ( |  | ) | const`[virtual]`

Clone.

Reimplemented from ClpCholeskyBase.

ClpCholeskyUfl& ClpCholeskyUfl::operator= | ( | const ClpCholeskyUfl & |  | ) | `[private]`

Assignment.

Reimplemented from ClpCholeskyBase.
