Download calculation of first 256 REAL valued Fourier coefficients of a closed function, separately for the "x" and "y" data. Attached is an example input. Input has to be ".dat" file. The first line is 1 (for 1 data set, can be modified), the next is the number of points, then the "x" and "y" coordinate dataset, with the last point being the same as the first. Output is a,b coefficients for x coordinate, c,d for y coordinate.
