A julia package containing the code to create the figures from Pointwise and uniform convergence of Fourier extensions by Marcus Webb, Vincent Coppé, and Daan Huybrechs.
Run the notebook to create the figures yourself, its prerequisit is a Julia 1.0 kernel. Since the calculations involve high accuracy floating point operations, part of the calculations are saved in /data. If you remove the files in that folder, the notebook will recreate them, but you will need some patience.
