This script allows for fast transformation between nodal and spectral values at the Chebyshev-Gauss-Lobatto points by using the built-in functions fft/ifft. I've tested it with truncation as high as N=2^20 and it takes 1.7820 seconds. This script will handle an arbitrary number of data sets of the same length simultaneously.
