I want to do a discrete fourier transform of the solution I have found using NDSolve, however, because the NDSolve creates Interpolating functions rather than numbers I can't do this. Any help is appreciated. I've attatched the file I'm working with.(adsbygoogle = window.adsbygoogle || []).push({});
