PSPCLINK - A COOPERATION BETWEEN GENERAL SYMBOLIC AND POISSON SERIES PROCESSORS

Poisson series appear frequently in problems of non-linear dynamics an d celestial mechanics. The size of such mathematical objects makes the ir manipulation by means of general symbolic processors (GSP) ineffici ent. Special processors named Poisson series processors (PSP) have bee n created to handle them in a more efficient way. We propose here a wa y to combine the flexibility and easy use of GSPs with the power of PS Ps. Using the communication tool MathLink we produced PSPCLink to conn ect Mathematica with PSPC, a PSP of our own creation. PSPCLink is a se t of C-files and one Mathematica package. Compiling the C-files we cre ated an executable program to be called from Mathematics. With PSPCLin k we use the PSPC functions in a way completely integrated into Mathem atics taking advantage of the good properties of both Mathematica and PSPC. (C) 1997 Academic Press Limited.
