Call the Lsqr algorithm.
ClpLsqr & operator=(const ClpLsqr &rhs)
Assignment operator. This copies the data.
This solves LPs using interior point methods.
Definition: ClpInterior.hpp:72
This class implements LSQR.

******** DATA to be moved into protected section of ClpInterior
Definition: ClpInterior.hpp:35
double * diag1_
Diagonal array 1.
Definition: ClpLsqr.hpp:92
ClpLsqr()
Default constructor.
******** DATA to be moved into protected section of ClpInterior
Definition: ClpInterior.hpp:27
bool setParam(char *parmName, int parmValue)
Set an int parameter.
void matVecMult(int, CoinDenseVector< double > *, CoinDenseVector< double > *)
Matrix-vector multiply - implemented by user.
void borrowDiag1(double *array)
diag1 - we just borrow as it is part of a CoinDenseVector&lt;double&gt;

Dense Vector.
int ncols_
Column dimension of matrix.
Definition: ClpLsqr.hpp:88
int nrows_
Row dimension of matrix.
Definition: ClpLsqr.hpp:86
double diag2_
Constant diagonal 2.
