◆ name()

template<typename TAlgebra >

virtual const char* ug::AgglomeratingPreconditioner< TAlgebra >::name ( ) const

inlinevirtual

returns the name of iterator

This method returns the name of the iterator operator. This function is typically needed, when the iterator operator is used inside of another operator and some debug output should be printed

Returns: const char* name of inverse operator

◆ preprocess()

template<typename TAlgebra >

virtual bool ug::AgglomeratingPreconditioner< TAlgebra >::preprocess ( SmartPtr< MatrixOperator< typename TAlgebra::matrix_type, typename TAlgebra::vector_type > > pOp )

inlinevirtual

initializes the preconditioner

This method is used to initialize the preconditioner. Usually, here are performed computationally expensive operations, that should only be computed once for an underlying matrix (e.g. LU factorization), while the preconditioner will by applied (using 'step'-method) several times.

Parameters

[in] mat underlying matrix (i.e. L in L*u = f)

Returns: bool success flag
