Applies the transpose of preconditioner to a vector.

Synopsis#

#include "petscksp.h" 
PetscErrorCode PCApplyTranspose(PC pc, Vec x, Vec y)

Collective

Input Parameters#

  • pc - the preconditioner context

  • x - input vector

Output Parameter#

  • y - output vector

Note#

For complex numbers this applies the non-Hermitian transpose.

Developer Note#

We need to implement a PCApplyHermitianTranspose()
