This contains 2 versions of the program stosolve. It is designed to run entirely from within Mathematica, but if emacs is not available a different text editor will need to be used to edit the files "stoparams.c" and "stoparams2.c" while using the program. The first version is in directory /flow, which is mean to concentrate on looking at the flows, and stores the noise file so that you can try different initial conditions with the same noise. You simily need to open the mathematica notebook called stosolve.nb. The second version is in directory /noise, which allows you to try different noise data on the same differential equations. Simply open the mathematica notebook stosolve2.nb. Please read the conditions of use and acknowledgements which follow.
