# PetscViewerPushFormat#

Sets the format for a PetscViewer.

## Synopsis#

#include "petscsys.h"
PetscErrorCode PetscViewerPushFormat(PetscViewer viewer, PetscViewerFormat format)


Logically Collective

## Input Parameters#

• viewer - the PetscViewer

• format - the format

## Notes#

Available formats include

• PETSC_VIEWER_DEFAULT - default format

• PETSC_VIEWER_ASCII_MATLAB - MATLAB format

• 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_NATIVE - store the object to the binary file in its native format (for example, dense matrices are stored as dense), for DMDA vectors displays vectors in DMDA ordering, not natural

• 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

• PETSC_VIEWER_ASCII_XML - saves the data in XML format, needed for PetscLogView() when viewing with PetscLogNestedBegin()

These formats are most often used for viewing matrices and vectors. Currently, the object name is used only in the MATLAB format.
