KSPSolveTranspose

Solves the transpose of a linear system.

Synopsis

#include "petscksp.h" 
PetscErrorCode  KSPSolveTranspose(KSP ksp,Vec b,Vec x)
Collective on KSP

Input Parameter

ksp - iterative context obtained from KSPCreate()
b - right hand side vector
x - solution vector

Notes

For complex numbers this solve the non-Hermitian transpose system.

This currently does NOT correctly use the null space of the operator and its transpose for solving singular systems.

Developer Notes

We need to implement a KSPSolveHermitianTranspose()

Keywords

solve, linear system
