jfftw.FFTWComplex.twoDimensional()
Method to take two-dimensional Complex FFT with the data supplied in a one-dimensional double array with real parts in even elements, and imaginary in the odd.Element i,j is located at Real part 2*(j*width + i) Imag part 2*(j*width + i) + 1 @param width the width of the data @param height the height of the data @param in the input data array to be transformed @param out the output data array, may be the same as in @param dirn direction +1 for forward, -1 to backward @return double[] the FFTed array @throws NullPointerException if null or zero length datasend. @throws IllegalArgumentException if width and height doesnot match the both array lengths.

Examples of jfftw.FFTWComplex.twoDimensional()

    FFTWComplex fft = new FFTWComplex();




    //    Take out-of -place forward fft, does not alter the data[]
    //    array.
    double[] ft = fft.twoDimensional(width,height,data,1,false);
         
    //    Take in place backwords fft  
    fft.twoDimensional(width,height,ft,-1,true);
    
    // Normalise...   (no default normalsiation when using FFTW)
