#include "petscsys.h" PetscErrorCode PetscViewerSetFormat(PetscViewer viewer,PetscViewerFormat format)Logically Collective on PetscViewer
This routine is deprecated, you should use PetscViewerPushFormat()/PetscViewerPopFormat()
| viewer | - the PetscViewer | |
| format | - the format |
| PETSC_VIEWER_DEFAULT | - default format | |
| PETSC_VIEWER_ASCII_MATLAB | - MATLAB format | |
| PETSC_VIEWER_ASCII_DENSE | - print matrix as dense | |
| PETSC_VIEWER_ASCII_IMPL | - implementation-specific format (which is in many cases the same as the default) | |
| PETSC_VIEWER_ASCII_INFO | - basic information about object | |
| PETSC_VIEWER_ASCII_INFO_DETAIL | - more detailed info about object | |
| PETSC_VIEWER_ASCII_COMMON | - identical output format for all objects of a particular type | |
| PETSC_VIEWER_ASCII_INDEX | - (for vectors) prints the vector element number next to each vector entry | |
| PETSC_VIEWER_ASCII_SYMMODU | - print parallel vectors without indicating the processor ranges | |
| PETSC_VIEWER_ASCII_VTK | - outputs the object to a VTK file | |
| PETSC_VIEWER_NATIVE | - store the object to the binary file in its native format (for example, dense matrices are stored as dense), DMDA vectors are dumped directly to the file instead of being first put in the natural ordering | |
| PETSC_VIEWER_DRAW_BASIC | - views the vector with a simple 1d plot | |
| PETSC_VIEWER_DRAW_LG | - views the vector with a line graph | |
| PETSC_VIEWER_DRAW_CONTOUR | - views the vector with a contour plot |
These formats are most often used for viewing matrices and vectors.
If a format (for example PETSC_VIEWER_DRAW_CONTOUR) was applied to a viewer where it didn't apply (PETSC_VIEWER_STDOUT_WORLD) it cause the default behavior for that viewer to be used.
Note: This supports passing in a NULL for the viewer for use in the debugger, but it should never be called in the code with a NULL viewer
