%COMPUTE_LONGER Vary the length of the transform % % This script computes the running time for longer and longer % transforms. Use the script plot_longer to visualize the result. % % All other parameters except L remain fixed. The window length for the % filter bank algorithm is also kept fixed. % % Copyright (C) 2005-2011 Peter L.
