PetscViewerHDF5GetAIJNames

Get the names of the datasets representing the three AIJ (CRS) arrays and the name of the attribute storing the number of columns within the HDF5 file.

Synopsis

#include "petscviewerhdf5.h"   
/* TODO Once corresponding MatView is implemented, add this:
  Current defaults are (iname, jname, aname, cname) = ("i", "j", "a", "ncols").
  For PetscViewerFormat PETSC_VIEWER_HDF5_MAT they are ("jc", "ir", "data", "MATLAB_sparse") so that MAT files can be loaded.
*/
PetscErrorCode  PetscViewerHDF5GetAIJNames(PetscViewer viewer, const char *iname[], const char *jname[], const char *aname[], const char *cname[])
Collective on PetscViewer

Input Parameters

viewer -the PetscViewer; either ASCII or binary

Output Parameters

iname - name of dataset i representing row pointers; that is i[0] = 0, i[row] = i[row-1] + number of elements in that row of the matrix
jname - name of dataset j representing column indices
aname - name of dataset a representing matrix values
cname - name of attribute stoting column count

Notes

Current defaults are (iname, jname, aname, cname) = ("jc", "ir", "data", "MATLAB_sparse") so that MAT files can be readily loaded.
