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?
