Member Function Documentation

◆ order()

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

If return code negative then out of memory

Reimplemented from ClpCholeskyBase.

◆ solve()

virtual void ClpCholeskyDense::solve ( CoinWorkDouble *  region)
virtual

Uses factorization to solve.

Reimplemented from ClpCholeskyBase.

◆ reserveSpace()

int ClpCholeskyDense::reserveSpace ( const ClpCholeskyBase factor,
int  numberRows

Returns space needed.

◆ factorizePart2()

void ClpCholeskyDense::factorizePart2 ( int *  rowsDropped)
