(

)

[virtual]

Member Function Documentation

virtual int ClpCholeskyWssmpKKT::order

(

ClpInterior *

model

)

[virtual]

Orders rows and saves pointer to matrix.and model.

Returns non-zero if not enough memory

Reimplemented from ClpCholeskyBase.

virtual int ClpCholeskyWssmpKKT::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 from ClpCholeskyBase.

virtual int ClpCholeskyWssmpKKT::factorize	(	const double *	diagonal,
		int *	rowsDropped
	)			[virtual]

Factorize - filling in rowsDropped and returning number dropped.

If return code negative then out of memory

Reimplemented from ClpCholeskyBase.

virtual void ClpCholeskyWssmpKKT::solve

(

double *

region

)

[virtual]

Uses factorization to solve.

Reimplemented from ClpCholeskyBase.

virtual void ClpCholeskyWssmpKKT::solveKKT	(	double *	region1,
		double *	region2,
		const double *	diagonal,
		double	diagonalScaleFactor
	)			[virtual]

Uses factorization to solve.

• given as if KKT. region1 is rows+columns, region2 is rows

Reimplemented from ClpCholeskyBase.

ClpCholeskyWssmpKKT& ClpCholeskyWssmpKKT::operator=

(

const ClpCholeskyWssmpKKT &

)

Constructor which has dense columns activated.

Default is off.

virtual ClpCholeskyBase* ClpCholeskyWssmpKKT::clone

(

)

const [virtual]

Clone.

Reimplemented from ClpCholeskyBase.
