Detailed Description

Abstract base class for handling fast Fourier transforms.

The tuner makes frequent use of fast Fourier transforms. However, existing packages such as fftw3 are not completely thread-safe. This adapter class establishes an interface between the tuner and a specific implementation.

The adapter is designed for two types of FFTs, namely, real to complex and comples to real. The second one is the inverse of the first one.
