GMatView

 Views a grid matrix.

Synopsis

#include "gvec.h" 
int GMatView(GMat mat, PetscViewer viewer)

Input Parameters

mat - the grid matrix
viewer - an optional visualization context

Notes

GMatView() supports the same viewers as MatView(). The only difference is that for all multiprocessor cases, the output vector employs the natural ordering of the grid, so it many cases this corresponds to the ordering that would have been used for the uniprocessor case.

The available visualization contexts include 

    VIEWER_STDOUT_SELF - standard output (default)

    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 user can open alternative visualization contexts with 

   PetscViewerFileOpenASCII() - output vector to a specified file

   PetscViewerFileOpenBinary() - output in binary to a

        specified file; corresponding input uses VecLoad()

   PetscViewerDrawOpenX() - output vector to an X window display

   DrawLGCreate() - output vector as a line graph to an X window display

   PetscViewerMatlabOpen() - output vector to Matlab viewer

Keywords
