I'm confused by what the professor means on this Fourier Series proble

  1. Mar 7, 2013 #1
    1. The problem statement, all variables and given/known data

    See the second bullet point on this page: http://facweb.northseattle.edu/rjenne/e240w13flr/hwflr/feb21/e240w13hwfeb21.pdf

    2. Relevant equations

    So I know that fft(x) for a bunch of sample points x={x1, x2, ..., xn} returns the n Fourier coefficients for a function fitted through those sample points.

    3. The attempt at a solution

    So I'm a little confused about what the 1/31 and the c mean in the context of this problem. What I'm trying to do, ultimately, is use the Fast Fourier Transform algorithm on 31 equally spaced sample points on the domain [1, 4] to reconstruct the function on 3001 equally spaced sample points on the same domain.

    Thoughts?

    How is the Fourier transform normalized? And can you see any link between what I put in bold there?

    Now I've figured out that problem, but I'm confused on a different problem where I have to use the MATLAB function odeset to change absolute and relative tolerance. Do you know how to do that?
