SOFTWARE GUIDE AND UNWRAPPING INSTRUCTIONS
(THIS SOFTWARE IS FOR THE USE OF
MATH 286 and MATH 294 STUDENTS AT UCSD ONLY)

For all of this software you will need a copy of Mathematica 4.0.
For the UNIX version, you will need access to C.
For the Windows NT version (stosolve.tar.gz), you will also
need Visual C++.


PROGRAMS TO RUN ON UNIX

ito.uue is  a uuencoded version of the symbolic manipulation software (this
is Wilfrid Kendall's software)

ustosolve.uue is a uuencoded version of the simulation software for sdes
(a combination of  Mathematica notebooks with Jessica Gaines' C code for 
simulation of sde solutions -- the notebooks were written by David Glickenstein)

You can unwrap these two programs 
using the following instructions on a UNIX system:

1. Save the appropriate file from the webpage to your UNIX account 
in the directory where you want to 
put the software.

2(a) To unwrap ito.uue execute the following commands:
   uudecode ito.uue
   gunzip ito.tar
   tar -xvf ito.tar
The software will be in the directory Itovsn3

2(b) To unwrap ustosolve.uue execute the following commands:
   uudecode ustosolve.uue
   gunzip ustosolve.tar
   tar -xvf ustosolve.tar
The software will be in the directory Stosolve


PROGRAMS TO RUN ON WINDOWS NT
The file
stosolve.tar.gz
is also on the web site -- this is a binary UNIX zipped and tared file
of the simulation software for Windows NT machines
(it seems to download fine, despite the fact that it is binary)
To unwrap the software, first save it to a directory on your UNIX account.
Then execute the following
   gunzip stosolve.tar
   tar -xvf stosolve.tar
The software will then be in the directory Stosolve.
You can then copy it to a Windows NT machine for use.                                             

Please let me know if you have trouble with or comments on these programs or the
downloading of them.
Use of this software is at your own risk. No guarantees are implied
by making this software available.
