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
