View source for CDE: a Reduce package for integrabilty of PDEs

The [[Media:Cde_GDEQ_141010.zip‎|Reduce package CDE]] (latest version: 1.0 10/10/2014) is written 'on top' of [[CDIFF]]. 
It is devoted to computations on quantities which are related with the integrability of general differential equations (i.e., not necessarily in evolution form) with an arbitrary number of dependent and independent variables. It can compute generalized symmetries, conservation laws, Hamiltonian, symplectic and recursion operators, with local and nonlocal coordinates. It is distributed under the same free license of REDUCE.

The above zip file contains:

* A README.txt file;
* The program file ''cde.red'', for computations of differential consequences of even and odd partial differential equations and of the related total derivatives.
* The file [[Media:Cde-userguide-1.0.pdf|Cde-userguide-1.0.pdf]], a CDE 1.0 user guide for computations of symmetries, conservation laws, Hamiltonian, symplectic and recursion operators, in local and nonlocal coordinates.
* The file ''global.txt'' with a list of global variables used in cde.red.
* The folder ''examples'', which contains all examples described in the user guide with results and debug files.

The author of the package, [[Raffaele Vitolo]], welcomes comments and questions on CDE (use the email raffaele.vitolo@unisalento.it).
