fftshift() function

[Diego Alberto Arias Prado]

        Hello.
        Theres in matlab a function called fftshift() that it isn't
implemented in octave. I have tried to do a fftshift for octave (a .m file)
but the results are not 100% satisfactory because the on-line documentation
(> help fftshift()) of matlab about this function is vague - mu fftshift()
shifts more or less than I desire. Could somebody help me?
        Thanks in advance.
