Classes
class	pism::FFTWArray

Namespaces
namespace	pism
namespace	pism::petsc
	Wrappers for some PETSc objects (these wrappers simplify memory management).

Functions
std::vector< double >	pism::fftfreq (int M, double normalization)
void	pism::clear_fftw_array (fftw_complex *input, int Nx, int Ny)
	Fill input with zeros.
void	pism::copy_fftw_array (fftw_complex *source, fftw_complex *destination, int Nx, int Ny)
	Copy source to destination.
void	pism::set_real_part (petsc::Vec &input, double normalization, int Mx, int My, int Nx, int Ny, int i0, int j0, fftw_complex *output)
void	pism::get_real_part (fftw_complex *input, double normalization, int Mx, int My, int Nx, int Ny, int i0, int j0, petsc::Vec &output)
	Get the real part of input and put it in output.
