KSPView

Prints the KSP data structure.

Synopsis

#include "petscksp.h" 
PetscErrorCode  KSPView(KSP ksp,PetscViewer viewer)
Collective on ksp

Input Parameters

ksp - the Krylov space context
viewer - visualization context

Options Database Keys

-ksp_view - print the ksp data structure at the end of a KSPSolve call

Note

The available visualization contexts include
PETSC_VIEWER_STDOUT_SELF - standard output (default)
PETSC_VIEWER_STDOUT_WORLD - synchronized standard output where only the first processor opens the file. All other processors send their data to the first processor to print.

The user can open an alternative visualization context with PetscViewerASCIIOpen() - output to a specified file.

In the debugger you can do "call KSPView(ksp,0)" to display the KSP. (The same holds for any PETSc object viewer).
