void PreconditionJacobi< MATRIX >::vmult | ( | VECTOR & | , |
const VECTOR & | |||
) | const |
Apply preconditioner.
void PreconditionJacobi< MATRIX >::Tvmult | ( | VECTOR & | , |
const VECTOR & | |||
) | const |
Apply transpose preconditioner. Since this is a symmetric preconditioner, this function is the same as vmult().
void PreconditionJacobi< MATRIX >::step | ( | VECTOR & | x, |
const VECTOR & | rhs | ||
) | const |
Perform one step of the preconditioned Richardson iteration.
void PreconditionJacobi< MATRIX >::Tstep | ( | VECTOR & | x, |
const VECTOR & | rhs | ||
) | const |
Perform one transposed step of the preconditioned Richardson iteration.
