Golden, August 5, 2009 Dear user, Instead of downloading all the files in the list, we recommend that you download the WinZipped (v. 8.1) file Diffdens2009.zip, which contains * Diffdens2009.m: the source code in Mathematica syntax, the sample notebook, * Diffdens--Documentation.nb: a notebook with a some instructions and a demo of the program for the Kac-van Moerbeke (a discretization of the Korteweg-de Vries equation), the various data files, for example, * d_kdv.m: the data file to run the Kac-van Moerbeke equation, as well as ALL other data files listed in the menu of the program (and a few extra ones). Instructions for using the Diffdens2009.m program should be obvious based on the menu system. Just execute the commands in the notebook. You need Mathematica v. 3.0 or higher to be able to use the program. Best wishes, Prof. Willy Hereman Department of Mathematical and Computer Sciences Colorado School of Mines Golden, CO 80401-1887, U.S.A.
