Constructor & Destructor Documentation
◆ ClpCholeskyUfl() [1/2]
| ClpCholeskyUfl::ClpCholeskyUfl | ( | int | denseThreshold = -1 | ) |
Constructor which has dense columns activated.
Default is off.

|
virtual |
Destructor
◆ ClpCholeskyUfl() [2/2]

Member Function Documentation
◆ order()
|
virtual |
Orders rows and saves pointer to matrix.and model.
Returns non-zero if not enough memory
Reimplemented from ClpCholeskyBase.
◆ 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.
◆ factorize()
|
virtual |
Factorize - filling in rowsDropped and returning number dropped using CHOLMOD (if available).
If return code negative then out of memory
◆ solve()
|
virtual |
Uses factorization to solve.
Uses CHOLMOD (if available).
◆ clone()
|
virtual |
Clone.
Reimplemented from ClpCholeskyBase.
