PETSC_i
the imaginary number i
Synopsis
#define PETSC_DESIRE_COMPLEX
#include
PetscComplex PETSC_i;
Note
Complex numbers are automatically available if PETSc was configured --with-scalar-type=complex (in which case
PetscComplex will match PetscScalar), otherwise the macro PETSC_DESIRE_COMPLEX must be defined before including any
PETSc headers. If the compiler supports complex numbers, PetscComplex and associated variables and functions will be
defined and PETSC_HAVE_COMPLEX will be set.
