Detailed Description

template<typename LAI, template< typename > class SOLVER>
class geos::InverseNormalOperator< LAI, SOLVER >

Wraps a matrix A and represents A^{-1} * A^{-T} as a linear operator.

Template Parameters

LAI	the linear algebra interface
SOLVER	type of solver used to apply inverse of the matrix

Definition at line 93 of file InverseNormalOperator.hpp.

Constructor & Destructor Documentation

InverseNormalOperator()

template<typename LAI , template< typename > class SOLVER>

geos::InverseNormalOperator< LAI, SOLVER >::InverseNormalOperator ( Matrix const &  mat, Solver const &  solver  )

inlineexplicit

Constructor.

Parameters

mat	the underlying matrix (must outlive this operator)
solver	the solver used to apply inverse of the matrix (must be already setup)
