FFTW++ provides a simple C++ interface for 1D, 2D, and 3D complex-to-complex, real-to-complex, and complex-to-real Fast Fourier Transforms that takes care of the technical aspects of memory allocation, alignment, planning, wisdom, and communication on both serial and parallel (OpenMP/MPI) architectures. Wrappers for multiple 1D transforms are also provided. As with the FFTW3 library, in-place and out-of-place multithreaded transforms of arbitrary size are supported. Hybrid dealiasing of standard and centered Hermitian convolutions is also implemented; implicit zero-padding substantially reduces memory usage and computation time. Parallelization is accomplished using an efficient adaptive OpenMP/MPI transpose routine. Wrappers for C, Python, and Fortran are included.
