void * factorization_
Taucs factor.
ClpCholeskyTaucs & operator=(const ClpCholeskyTaucs &)
Default constructor.
char * rowsDropped() const
rowsDropped - which rows are gone
Base class for Clp Cholesky factorization Will do better factorization.
longDouble * diagonal() const
Return diagonal.
Taucs class for Clp Cholesky factorization.
CoinBigIndex sizeFactorT_
sizeFactor.
This solves LPs using interior point methods.

virtual int order(ClpInterior *model)
Orders rows and saves pointer to matrix.and model.
virtual ~ClpCholeskyTaucs()
Destructor.
virtual int symbolic()
Dummy.
virtual int factorize(const double *diagonal, int *rowsDropped)
Factorize - filling in rowsDropped and returning number dropped.
Abstract base class for Clp Matrices.
int * choleskyRowT_
choleskyRow
taucs_ccs_matrix * matrix_
Taucs matrix (== sparseFactor etc)
virtual ClpCholeskyBase * clone() const
Clone.
ClpMatrixBase * rowCopyT_
Row copy of matrix.
virtual void solve(double *region)
Uses factorization to solve.
double * sparseFactorT_
sparseFactor.
CoinBigIndex * choleskyStartT_
choleskyStart
ClpCholeskyTaucs()
Default constructor.
