Constructor & Destructor Documentation

◆ ClpCholeskyMumps() [1/2]

ClpCholeskyMumps::ClpCholeskyMumps ( int  denseThreshold = -1,
int  logLevel = 0 
)

Constructor which has dense columns activated.

Default is off.

◆ ~ClpCholeskyMumps()

virtual ClpCholeskyMumps::~ClpCholeskyMumps ( )
virtual

Destructor

◆ ClpCholeskyMumps() [2/2]

ClpCholeskyMumps::ClpCholeskyMumps ( const ClpCholeskyMumps )
private

Member Function Documentation

◆ order()

virtual int ClpCholeskyMumps::order ( ClpInterior model)
virtual

Orders rows and saves pointer to matrix.and model.

Returns non-zero if not enough memory

Reimplemented from ClpCholeskyBase.

◆ symbolic()

virtual int ClpCholeskyMumps::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.

◆ factorize()

virtual int ClpCholeskyMumps::factorize ( const double *  diagonal,
int *  rowsDropped 
)
virtual

Factorize - filling in rowsDropped and returning number dropped.

If return code negative then out of memory

◆ solve()

virtual void ClpCholeskyMumps::solve ( double *  region)
virtual

Uses factorization to solve.

◆ clone()

virtual ClpCholeskyBase* ClpCholeskyMumps::clone ( ) const
virtual

Clone.

Reimplemented from ClpCholeskyBase.

◆ operator=()

ClpCholeskyMumps& ClpCholeskyMumps::operator= ( const ClpCholeskyMumps )
private
