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).
