[petsc-users] external binary reader from bin/matlab

      I assume you mean dense matrices written with  
PETSC_VIEWER_NATIVE option to the viewer?

      Please find attached a version of PetscBinaryRead.m that handles  
this. Please let me know if it doesn't work for you?

     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.
