Detailed Description

template<class InputStorageType, class OutputStorageType>
class BIAS::FFT2D_Tiles< InputStorageType, OutputStorageType >

Wrapper to the fftw3 library, which is supposed to perform the FFT patch- (tile-) wise.

Attention
This class is practically NOT implemented!
Note
Use fast as follows:
Todo:
remove FFT2D_Tiles or really implement it. (JW)
