Detailed Description

Taucs class for Clp Cholesky factorization.

If you wish to use Sivan Toledo's TAUCS code see

for terms of use

The taucs.h file was modified to put

#ifdef __cplusplus extern "C"{ #endif after line 440 (#endif) and #ifdef __cplusplus } #endif at end

I also modified LAPACK dpotf2.f (two places) to change the GO TO 30 on AJJ.Lt.0.0

to

IF( AJJ.LE.1.0e-20 ) THEN AJJ = 1.0e100; ELSE AJJ = SQRT( AJJ ) END IF

Constructor & Destructor Documentation

ClpCholeskyTaucs::ClpCholeskyTaucs ( )

Default constructor.

virtual ClpCholeskyTaucs::~ClpCholeskyTaucs ( ) [virtual]

Destructor.

ClpCholeskyTaucs::ClpCholeskyTaucs ( const ClpCholeskyTaucs & )

virtual int ClpCholeskyTaucs::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 ClpCholeskyTaucs::symbolic ( ) [virtual]

Dummy.

Reimplemented from ClpCholeskyBase.

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

Factorize - filling in rowsDropped and returning number dropped.

If return code negative then out of memory

virtual void ClpCholeskyTaucs::solve ( double * region ) [virtual]

Uses factorization to solve.

ClpCholeskyTaucs& ClpCholeskyTaucs::operator= ( const ClpCholeskyTaucs & )

virtual ClpCholeskyBase* ClpCholeskyTaucs::clone ( ) const [virtual]

Clone.

Reimplemented from ClpCholeskyBase.
