as you said, I was using PETSC_VIEWER_NATIVE for parallel rectangular dense
matrix. As far as I can remember, I switched to that option because some cases
didn't run in parallel otherwise or something like that.... Didn't raise a bug
report because we are still in 2.3.3 for multiple tangled reasons.<o:p></o:p></span></p>

<p class=MsoNormal> Please find attached a version of

you?<o:p></o:p></p>

<p class=MsoNormal> Notes: the default viewing of dense
matrices converts to sparse so that PetscBinaryRead() does actually work.
The reading of native dense format doesn't matter if the matrix is
rectangular or square it just was not supported (but is with my new code).
Please let me know if I misunderstood your problem.<o:p></o:p></p>
