A Maple package for finding exact solitary wave solutions of coupled nonlinear evolution equations Original Research Article

The tanh function expansion method for finding traveling solitary wave solutions to coupled nonlinear evolution equations is described. A complete implementation RATHS written in Maple is presented, in which the operator mains can output exact solitary wave solutions entirely automatically. Furthermore, RATHS can handle any number of dependent variables ui as well as any number of independent variables xj contained in the input system. This package can also be applied to ODEs. The effectiveness of RATHS is illustrated by applying it to a variety of equations.
