Hey everyone,
Ok, my ultimate aim is analysis of gamma ray burst light curves, so i have data which includes count rate in a certain energy range recorded every 64 ms. I would like to apply some kind of discrete, numerical fourier transform to this long list of data, in order to produce a new graph that tells me something about frequencies present. I'm not at all sure how to go about doing this for a finite list of numbers, since all info i can find on fourier transforms is in terms of integrals and functions...any help at all would be greatly appreciated!!!
