Hello all, first time here and I have really silly problem... I am working on something in MATLAB, in which I have to make discrete fourier transform of gaussian distributed variable. i.e. array of numbers which are taken from f(x)~exp(-x^2). I know that when you fourier transform it with integral you get the same distribution in k-space. i.e. f(k)~exp(-k^2), but in the discrete transform I get the distribution something like f(k)~sin(k)exp(-k^2)... help!! someone... why? Thnx, The Samurai.
