virtual int factorize(const double *diagonal, int *rowsDropped)
Factorize - filling in rowsDropped and returning number dropped.
Abstract base class for Clp Matrices.
This solves LPs using interior point methods.
Definition: ClpInterior.hpp:72
char * rowsDropped() const
rowsDropped - which rows are gone
virtual ~ClpCholeskyWssmp()
Destructor.
ClpCholeskyWssmp(int denseThreshold=-1)
Constructor which has dense columns activated.
virtual int symbolic()
Does Symbolic factorization given permutation.
Base class for Clp Cholesky factorization Will do better factorization.
ClpCholeskyWssmp & operator=(const ClpCholeskyWssmp &)
virtual int order(ClpInterior *model)
Orders rows and saves pointer to matrix.and model.
virtual ClpCholeskyBase * clone() const
Clone.
longDouble * diagonal() const
Return diagonal.
Wssmp class for Clp Cholesky factorization.
virtual void solve(double *region)
Uses factorization to solve.
