virtual int ClpCholeskyBase::order ( ClpInterior * model )

virtual

Orders rows and saves pointer to matrix.and model.

returns non-zero if not enough memory. You can use preOrder to set up ADAT If using default symbolic etc then must set sizeFactor_ to size of input matrix to order (and to symbolic). Also just permute_ and permuteInverse_ should be created

Reimplemented in ClpCholeskyTaucs, ClpCholeskyUfl, ClpCholeskyMumps, ClpCholeskyWssmp, ClpCholeskyWssmpKKT, and ClpCholeskyDense.

virtual int ClpCholeskyBase::symbolic ( )

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 in ClpCholeskyTaucs, ClpCholeskyUfl, ClpCholeskyMumps, ClpCholeskyWssmp, ClpCholeskyWssmpKKT, and ClpCholeskyDense.

virtual int ClpCholeskyBase::factorize	(	const CoinWorkDouble *	diagonal,
		int *	rowsDropped
	)

virtual

Factorize - filling in rowsDropped and returning number dropped.

If return code negative then out of memory

Reimplemented in ClpCholeskyTaucs, ClpCholeskyUfl, ClpCholeskyMumps, ClpCholeskyWssmp, ClpCholeskyWssmpKKT, and ClpCholeskyDense.

virtual void ClpCholeskyBase::solve ( CoinWorkDouble * region )

virtual

Uses factorization to solve.

Reimplemented in ClpCholeskyTaucs, ClpCholeskyUfl, ClpCholeskyMumps, ClpCholeskyWssmp, ClpCholeskyWssmpKKT, and ClpCholeskyDense.

virtual void ClpCholeskyBase::solveKKT	(	CoinWorkDouble *	region1,
