◆ linear_solver()

bool CGAL::Eigen_solver_traits< Eigen::BiCGSTAB< Eigen_sparse_matrix< double >::EigenType > >::linear_solver ( const Matrix A,
const Vector B,
Vector X,
NT D 
)

Solve the sparse linear system \( A \times X = B \).

Return true on success. The solution is then \( (1/D) \times X \).

Precondition
A.row_dimension() == B.dimension().
A.column_dimension() == X.dimension().

◆ solver()

EigenSolverT& CGAL::Eigen_solver_traits< Eigen::BiCGSTAB< Eigen_sparse_matrix< double >::EigenType > >::solver ( )

Returns a reference to the internal Eigen solver.

This function can be used for example to set specific parameters of the solver.
