Member Function Documentation

clear()

void Empty_Precond::clear ( void  )

inlinevirtual

Clear preconditioner.

Clears preconditioner. Both prepare() and construct() functions have to be called after this.

Implements Precond.

construct()

void Empty_Precond::construct ( const CRowMatrix &  A )

inlinevirtual

Construct preconditioner for matrix A.

Implements Precond.

copy()

Empty_Precond* Empty_Precond::copy ( void  ) const

inlinevirtual

Get a new copy of preconditioner.

Implements Precond.

is_prepared()

bool Empty_Precond::is_prepared ( void  ) const

inlinevirtual

Return false if prepare is needed.

Returns true if prepare is not needed and false if it is.

Implements Precond.

prepare()

void Empty_Precond::prepare ( const CRowMatrix &  A )

inlinevirtual

Prepare preconditioner for matrices with non-zero pattern equal to A.

Implements Precond.

solve()

void Empty_Precond::solve ( Vector &  x, const Vector &  b  ) const

inlinevirtual

Return x = b.

Implements Precond.

typestring()

std::string Empty_Precond::typestring ( void  ) const

inlinevirtual

Return string indicating type of preconditioner.

Implements Precond.
