edu.emory.mathcs.jtransforms.fft.DoubleFFT_1D.realForwardFull()
mikera.matrixx.algo.FFT.realForwardFull()
Computes 1D forward DFT of real data leaving the result in a . This method computes the full real forward transform, i.e. you will get the same result as from complexForward called with all imaginary parts equal 0. Because the result is stored in a, the size of the input array must greater or equal 2*n, with only the first n elements filled with real data. To get back the original data, use complexInverse on the output of this method. @param a data to transform
