some worry about FFT's half result

Hi,Intel masters,

  I am writing to ask for information about the FFT's half result . In matlab,i use fft to compute an real array ,and then use ifft ,i'll get the initial array.However , in MKL, i just coule get a N/2 + 1 result. Could I had some configs to got the full result? If not ,maybe i could to Conj the  first half of the result to fill the second result and reverse that ,because of the fft oufput in matlab , that is mirroring .

I would be grateful to receive a prompt reply and I am sorry for my broken English.

thanks,xD.

you may look at the fft examples ( mklroot/examples/dft[c,f]. there you may find out some examples show how to take such results.
