Orders rows and saves pointer to matrix.and model.
Returns non-zero if not enough memory
Reimplemented from ClpCholeskyBase.
|
virtual |
Does Symbolic factorization given permutation.
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.
