I apologize if this is a basic question, but here goes: The Discrete Fourier transform of a sequence of N complex numbers is uniquely defined by eq.1 in this wiki page,
There are no parameters in this definition of the Fourier transform. So why does the Fourier command in Mathematica need two parameters? I've looked at the Mathematica documentation, but can't find an explanation. Thanks for any help. Please pardon my lack of insight here.
