Re: Fourier function...having problems reproducing answers in a paper


Hi, there are several equivalent definitions of the discrete Fourier
transform in the literature. To reproduce the result in your paper use the
FourierParameters option.

Fourier[{.5,0,.4,0,0,.1}, FourierParameters -> {1,-1}]

Hi there,

I am using the Fourier function on a simple list probability
distribution {.5,0,.4,0,0,.1}.  The paper I'm reading says I should be
geting an answer like this:

{1, .35-.2598i, .25+.433i, .8, .25-.433i, .35+.2598i}.

However this is what Mathematica is returning:

{.408248 + i,  .142887 + .106066i, .102062 - .176777i .326599 + i,
.102062 + .17677i, .142887 - .106066i }

I assume that these are somehow equivilant.  Can some explain how/why?
