Detailed Description

template<typename LAI>
class geos::TransposeOperator< LAI >

Simple class that wraps a matrix and represents its transpose as a linear operator.

Template Parameters

LAI	the linear algebra interface

Definition at line 32 of file TransposeOperator.hpp.

Constructor & Destructor Documentation

◆ TransposeOperator()

template<typename LAI >

geos::TransposeOperator< LAI >::TransposeOperator ( Matrix const & mat )

inlineexplicit

Constructor.

Parameters

mat	the underlying matrix

Definition at line 49 of file TransposeOperator.hpp.

Member Function Documentation

◆ apply()

template<typename LAI >

virtual void geos::TransposeOperator< LAI >::apply	(	Vector const &	src,
		Vector &	dst
	)		const

inlineoverridevirtual

Apply operator to a vector.

Parameters

src	input vector (x)
dst	output vector (b)

Warning: src and dst cannot alias the same vector (some implementations may allow this).

Definition at line 66 of file TransposeOperator.hpp.

◆ comm()

template<typename LAI >

virtual MPI_Comm geos::TransposeOperator< LAI >::comm ( ) const

inlineoverridevirtual

Get the MPI communicator the matrix was created with.

Returns: MPI communicator of the underlying matrix

Definition at line 111 of file TransposeOperator.hpp.

◆ numGlobalCols()

template<typename LAI >

virtual globalIndex geos::TransposeOperator< LAI >::numGlobalCols ( ) const

inlineoverridevirtual

Get the number of global columns.

Returns: Number of global columns in the operator.

Definition at line 84 of file TransposeOperator.hpp.

◆ numGlobalRows()

template<typename LAI >

virtual globalIndex geos::TransposeOperator< LAI >::numGlobalRows ( ) const

inlineoverridevirtual

Get the number of global rows.

Returns: Number of global rows in the operator.

Definition at line 75 of file TransposeOperator.hpp.

◆ numLocalCols()

template<typename LAI >

virtual localIndex geos::TransposeOperator< LAI >::numLocalCols ( ) const

inlineoverridevirtual

Get the number of local columns.

Returns: Number of local columns in the operator.

Definition at line 102 of file TransposeOperator.hpp.
