[petsc-dev] PETSc VecView with MPIIO and complex numbers broken?

[Dave May]

Hi Barry,

I fixed all the PetscPrintf's to have the (double) cast.
I am wondering if this could this be an uninitialized variable issue?

In that code, I have the following declaration

  const PetscScalar test_values[] = { 0.311256, 88.068, 11.077444,
9953.62, 7.345, 64.8943, 3.1458, 6699.95, 0.00084, 0.0647 };

which is then used to build a Vec object.
I am not explicitly setting the imaginary part of the vector to zero when
test_values is declared.

Apologize for the crappy code -  I really never ever use complex numbers in
petsc.

If this is in fact the issue, please note that the same time of declaration
appears at the top of
  petsc / src / dm / examples / tutorials / ex15.c


Cheers
   Dave
