Class InverseFFT

java.lang.Object
  |
  +--InverseFFT

The InverseFFT class contains a method to apply the 2D inverse FFT to a TwoDArray.

Constructor Summary
`InverseFFT()` Default no argument constructor.

Method Summary
`ComplexNumber[]`	`recursiveInverseFFT(ComplexNumber[] x)` Recursively applies the 1D inverse FFT algorithm.
`TwoDArray`	`transform(TwoDArray input)` Takes a TwoDArray, applies the 2D inverse FFT to the input by applying the 1D inverse FFT to each column and then each row in turn.

Method Detail

public ComplexNumber[] recursiveInverseFFT(ComplexNumber[] x)

Recursively applies the 1D inverse FFT algorithm.

Parameters:: x - ComplexNumber array containing the input to the 1D inverse FFT.
Returns:: ComplexNumber array containing the result of the 1D inverse FFT.

public TwoDArray transform(TwoDArray input)

Takes a TwoDArray, applies the 2D inverse FFT to the input by applying the 1D inverse FFT to each column and then each row in turn.
