Programs for Mathematica


1. Package Chasing  (designed for usage with Mathematica ver. 3 and 4) provide tools for numerical solution of linear boundary value problems and
    linear boundary eigenvalue problems using the so-called method of chasing. Mathematica 5.0 and higher uses the algorithm from the Chasing
    for implementation  of numerical solution of linear boundary value problems, but the eigenproblems can be solved only with the Chasing package.


2. Package Replacement of Variables  works with both ordinary and partial differential equations
    making difficult cases simpler, and thus leading to new solutions.

Here is the example of usage of the Replacement of Variables package.
