I haven't had much succes in comp.lang.fortran, math, ... SO is thought I'd try my usual source of information. I am writing some petroleum engineering applications (related to graphics r&d and ||processing) and I need to solve some laplace tranforms. All of the techniques I've seen are solvable by paper and pencil, but have not easily been modeled in an algorithm (that could be computer solvable). I am looking for PD software, algorithms, or references to this domain area. I am using both C and C++ with X windows as a working environment. Thanks for the help in advance. pcb@usl.usl.edu csnet

Dr. Barry D. Ganapol gave a paper at the ANS summer meeting. The paper was titled _The Solution to the Nuclear Reactor Kinetic Equations with a Continuous Slowing Down Model Using Numerical Laplace Transform Inversion_. He evaluates the inversion on the Bromwich contour and uses some change of variables. There isn't enough detail in the transactions for me to understand the method, but I can send a copy if you want. You might want to do a literature search for other papers written by Dr. Ganapol or contact him at the University of Arizona. -- Mike Caldwell (mike@pmafire) Paths: ...uunet!pmafire!mike | ...!ucdavis!egg-id!pmafire!mike
