Member Function Documentation

void MultiresPreconditioner::multiply ( const cArrayView  p, cArrayView  q  ) const

inlinevirtual

This function implements matrix multiplication by the matrix of the set of equations that is to be solved.

Implements PreconditionerBase.

void MultiresPreconditioner::precondition ( const cArrayView  r, cArrayView  z  ) const

virtual

This function preconditions the equation, solving the preconditioner equation

\[ \mathbf{M}\mathbf{z} = \mathbf{r} \ . \]

It may use the MPI environment.

Implements PreconditionerBase.

RadialIntegrals const& MultiresPreconditioner::rad ( ) const

inlinevirtual

Implements PreconditionerBase.

void MultiresPreconditioner::rhs ( cArrayView  chi, int  ienergy, int  instate  ) const

inlinevirtual

Implements PreconditionerBase.

void MultiresPreconditioner::setup ( )

inlinevirtual

This function contains all computation intensive preparations for the preconditioner, e.g. computation of radial integrals. It may use only SMP environment.

Implements PreconditionerBase.

void MultiresPreconditioner::update ( double  E )

inlinevirtual

This function updates the preconditioner for another right hand side. It may use the MPI environment.

Implements PreconditionerBase.
