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}] Regards, Mariusz >>> elparedblanco<cire1611 at gmail.com> 2/8/2005 5:46:58 AM >>> 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?
