Limitations of the FFTW2 Interface to Intel MKL

The FFTW2 wrappers implement the functionality of only those FFTW functions that Intel MKL can reasonably support. Other functions are provided as no-operation functions, whose only purpose is to satisfy link-time symbol resolution. Specifically, no-operation functions include:

  • Real-to-half-complex and respective backward transforms

  • Print plan functions

  • Functions for importing/exporting/forgetting wisdom
