<H3><FONT COLOR="#CC3333">Note</FONT></H3>
Complex numbers are automatically available if PETSc was configured --with-scalar-type=complex (in which case
<A HREF="../Sys/PetscComplex.html#PetscComplex">PetscComplex</A> will match <A HREF="../Sys/PetscScalar.html#PetscScalar">PetscScalar</A>), otherwise the macro PETSC_DESIRE_COMPLEX must be defined before including any
PETSc headers. If the compiler supports complex numbers, <A HREF="../Sys/PetscComplex.html#PetscComplex">PetscComplex</A> and associated variables and functions will be
defined and PETSC_HAVE_COMPLEX will be set.
