void | BCGSP (const LinearOperator &mat, const real *rhs, real *x, Monitor &monitor, Allocator &allocator)
| Bi-Conjugate Gradient Stabilized with Preconditionning.

## Detailed Description

The linear system (and the preconditionner) is defined by class LinearOperator:

class LinearOperator
{
public:
unsigned int size() const;
void multiply(const real*, real*) const;
void transMultiply(const real*, real*) const;
void precondition(const real*, real*) const;
};

The iterative solver is followed by class Monitor, where the desired convergence criteria can be specified. Monitor will also keep track of iteration counts. An suitable implementation of Monitor is given here.
