This solves LPs using interior point methods.
This class implements LSQR.
Definition ClpLsqr.hpp:75
void matVecMult(int, CoinDenseVector< double > *, CoinDenseVector< double > *)
Matrix-vector multiply - implemented by user.
bool setParam(char *parmName, int parmValue)
Set an int parameter.
ClpLsqr(const ClpLsqr &)
Copy constructor.
double * diag1_
Diagonal array 1.
Definition ClpLsqr.hpp:91
void matVecMult(int, CoinDenseVector< double > &, CoinDenseVector< double > &)
void do_lsqr(CoinDenseVector< double > &b, double damp, double atol, double btol, double conlim, int itnlim, bool show, Info info, CoinDenseVector< double > &x, int *istop, int *itn, Outfo *outfo, bool precon, CoinDenseVector< double > &Pr)
Call the Lsqr algorithm.
ClpLsqr & operator=(const ClpLsqr &rhs)
Assignment operator. This copies the data.
~ClpLsqr()
Destructor.
int nrows_
Row dimension of matrix.
Definition ClpLsqr.hpp:85
ClpLsqr(ClpInterior *model)
Constructor for use with Pdco model (note modified for pdco!!!!)
ClpLsqr()
Default constructor.
double diag2_
Constant diagonal 2.
Definition ClpLsqr.hpp:93
int ncols_
Column dimension of matrix.
Definition ClpLsqr.hpp:87
void borrowDiag1(double *array)
diag1 - we just borrow as it is part of a CoinDenseVector<double>
Definition ClpLsqr.hpp:124
ClpInterior * model_
Pointer to Model object for this instance.
