I think I had already clarified what I meant:

If you need more details see here about top posting:

 https://en.wikipedia.org/wiki/Top-posting#Top-posting

On this list we prefer either bottom posting:

 https://en.wikipedia.org/wiki/Top-posting#Bottom-posting

or interleaved style:

because the list is archived and those styles make the archived discussions easier to follow.

Ys, now I got what is top posting. Is this is the right method?

I have a  set of samples in an array and want to do the fft function and want to collect back to an array. This is my need. How can I implement this? I am tried to as given below.

   fp = fopen("buffer","r");

  if (fp == NULL)

   return 0;

  for (ucI=0;ucI< 1024;ucI++)

   fscanf(fp,"%d\n",&InData[ucI]);

  octave_value_list input;

  for (int i = 0; i < 1024; i++)

  {

      input (i) = InData[i];

  }

  octave_value_list output = feval ("fft", input, 1024);

Is this is the right method? How can I collect the output to an array?
