KSPMatSolveTranspose#

Solves a linear system with the transposed matrix with multiple right-hand sides stored as a MATDENSE. Unlike KSPSolveTranspose(), B and X must be different matrices and the transposed matrix cannot be assembled explicitly for the user.

Synopsis#

#include "petscksp.h" 
#include "petscmat.h" 
PetscErrorCode KSPMatSolveTranspose(KSP ksp, Mat B, Mat X)

Input Parameters#

  • ksp - iterative context

  • B - block of right-hand sides

Output Parameter#

  • X - block of solutions

Notes#

This is a stripped-down version of KSPSolveTranspose(), which only handles -ksp_view, -ksp_converged_reason, -ksp_converged_rate, and -ksp_view_final_residual.
