Fix/Edit manual page

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 available formats include

PETSC_VIEWER_DEFAULT - standard output (default)
PETSC_VIEWER_ASCII_INFO_DETAIL - more verbose output for PCBJACOBI and PCASM

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).
