# 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).
