메소드	설명
DFT ( Complex data, Direction direction ) : void	One dimensional Discrete Fourier Transform.
DFT2 ( Complex data, Direction direction ) : void	Two dimensional Discrete Fourier Transform.
FFT ( Complex data, Direction direction ) : void	One dimensional Fast Fourier Transform. The method accepts data array of 2ⁿ size only, where n may vary in the [1, 14] range.
FFT2 ( Complex data, Direction direction ) : void	Two dimensional Fast Fourier Transform. The method accepts data array of 2ⁿ size only in each dimension, where n may vary in the [1, 14] range. For example, 16x16 array is valid, but 15x15 is not.
