Constructor & Destructor Documentation

ClpCholeskyUfl::ClpCholeskyUfl ( int denseThreshold = -1 )

Constructor which has dense columns activated.

Default is off.

virtual ClpCholeskyUfl::~ClpCholeskyUfl ( )

virtual

Destructor.

ClpCholeskyUfl::ClpCholeskyUfl ( const ClpCholeskyUfl & )

private

Member Function Documentation

virtual int ClpCholeskyUfl::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 ClpCholeskyUfl::symbolic ( )

virtual

Does Symbolic factorization given permutation using CHOLMOD (if available).

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 ClpCholeskyUfl::factorize	(	const double *	diagonal,
		int *	rowsDropped
	)

virtual

Factorize - filling in rowsDropped and returning number dropped using CHOLMOD (if available).

If return code negative then out of memory

Reimplemented from ClpCholeskyBase.

virtual void ClpCholeskyUfl::solve ( double * region )

virtual

Uses factorization to solve.

Uses CHOLMOD (if available).

Reimplemented from ClpCholeskyBase.

virtual ClpCholeskyBase* ClpCholeskyUfl::clone ( ) const

virtual

Clone.

Reimplemented from ClpCholeskyBase.

ClpCholeskyUfl& ClpCholeskyUfl::operator= ( const ClpCholeskyUfl & )
