KSPSolveTranspose#

Solves a linear system with the transpose of the matrix, \( A^T x = b\).

Synopsis#

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

Collective

Input Parameters#

  • ksp - iterative context obtained from KSPCreate()

  • b - right hand side vector

  • x - solution vector

Note#

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

Developer Note#

We need to implement a KSPSolveHermitianTranspose()
