Code to accompany the paper Diffractons: solitary waves created by diffraction in periodic media, by D. I. Ketcheson and M. Quezada de Luna. Published in SIAM MM&S; the free preprint is also available on the arXiv.

Subdirectories:

• pyclaw: Code and data for Figures 3, 5, (9,10,11), 13, and 14, which show results of PyClaw simulations.
• spectral: Code and data for Figures 4 and 12, which show results of pseudospectral simulations.
• scaling: Code and data for Figures 7-8. Only post-processing scripts are provided; if you wish to re-generate the data, use the code for Figure 5 (from the pyclaw directory).
• speed: Code and data for Figure 6. Again if you wish to re-generate the data, use the code for Figure 5.

Note that the data for Figure 14 has been compressed. You must uncompress it first if you wish to plot it.
