[petsc-dev] printing matlab vectors

[Mark Adams]

I do this:

  call
VecCreateSeqWithArray(PETSC_COMM_SELF,ione,n64,phi,vec,ierr);CHKERRQ(ierr)
  call PetscViewerASCIIOpen(PETSC_COMM_SELF, file_name,
viewer,ierr);CHKERRQ(ierr)
  call
PetscViewerSetFormat(viewer,PETSC_VIEWER_ASCII_MATLAB,ierr);CHKERRQ(ierr)
  call PetscObjectSetName(viewer,vec_name,ierr);CHKERRQ(ierr)
  call VecView(vec,viewer,ierr);CHKERRQ(ierr)

But I still get this:

05:51 nid02816 new_em *= ~/epsi/XGC-1_examples/em_tearing$ head xgc_lhs.m
%Vec Object: 1 MPI processes
%  type: seq
Vec_0xc4000009_0 = [
-0.0000000000000000e+00
5.6929682630215887e-16

Am I missing something?  I want Vec_0xc4000009_0 to be 'vec_name'
