I am guessing that you cannot get them to approve re-installing an old version after you have the new version unless you and they are having a really nice day at exactly the same time or unless you are very well known and they think they will benefit from doing you a favor. From skimming the description of how to do this I think I remember that you needed to have the old version installed and working and then gently sidestep the install process to be able to keep both. I have heard, but never figured out the details to actually be able to do this, that you can keep an old version installed and be able to use it after you install a new version. I know my role in life is to make it smell different from anyone else's fire hydrant, even different from a previous version of a fire hydrant that I might have written myself and certainly different from anything anyone else ever wrote, even if it seems to you like it should only make sense to have the same functionality." And those will be different in V9 and those will be different in V10 in a few weeks.ī: "I are software writer. Why can't I get the same effect in mathematica 8?Ī: Because you/we haven't found just the right combination of options, documented, semi-documented and undocumented, in Mathematica V8 that reproduces the old V5 behavior that you want, if that exact behavior is still even possible. But mathematica 5 doesn't have all other plot functions like 3d contour plot. Flattening creates a 445 Math Specialists 9. The plot on the right was done on mathematica 5. Using Mathematica for ODEs, Part 1 (Use DSolve and Plot for In this command, you define the differential equation that you want to solve and the initial conditions (the respective x and y values).
