  1. Supplementary figures

  2. Discussion of technical details of DWT method used in paper

  3. Code to compute W matrices

(Note: In this paper, these W matrices were not used to compute the empirical wavelet coefficients, but rather the pyramid-based DWT, which is much faster.  The reason for this code is to explore the properties of the transform for various boundary conditions and approaches for dealing with a non-power of two.  This was used in the document in 2 above.
