jfftw.FFTWReal.twoDimensionalBackward()

Method to take the two dimensional backward DFT of a hermition complex DFT held in a double array with real/imag parts in even/odd elements, with the k,l Complex components held as follows:

Real part located at 2(j * wft + i)
Imag part located at 2(j * wft + i) + 1
where wft = width/2 + 1.

The transformed real data is returned in a one-dimension double array with pixel i,j located at element j*width + i. @param width the image width @param height the image height @param complexArray the Fourier data packed in a 1-d array. @param realArray the returned real data of length width*height. If null or wrong length, then a new array will be created. @return double[] DFT packed into one dimensional array @throws IllegalArgumentException ifwidth*height is not consistent with array length.
