I'm suggesting a challenge to someone who can create a simulation in Maple on a local economy when a large supercenter enters, first, a localized small area (town), then the effect on a much larger population (state / country / etc...).  A sort of local vs. large businesses.

I would like to create a business model that shows the eventual crash of rich economies due to the increased reliance on foreign imports from poor economies.  As an example, perhaps...

I decided to graph the 649 as a set of single numbers just for fun.  However with my code at 4 numbers Maple 12 stops responding the memory is at 1426 M and 337 sec.   Most likely better with Maple 15, but probably a memory issue after all plotting 49*48*47*46*45*44 = 10068347520 points is a lot of points.

Here is what I have for the first three numbers.


a:=table():
l:=1:
for i from 1 to 49 do
  for j from 1 to 49 do
   for k from 1 to 49 do

Three things - one being an possible business opportunity (albeit a small one) for Maplesoft ... ps. sorry for the lengthy talk

updates - Under the Table of Contents in the help Browser I can go to System -> Information -> Updates and find the What's New updates in all versions up to and including the one you're using.  Then at the bottom there are links to further explicit updates to which there are no links in the searchable browser (at least that I could...

How do I edit a large proc to replace a couple of lines or add a few more if I don't save it and the screen was cleared?  Am I out of luck and have to retype it all back in?

And how do I substitute in a proc n_pts<5 to n_pts<5  or say substitute i=50 to i=30 .  I'm stuck with the operators.  I thought using delayed evaluation would work.  ie/  newproc:=subs( 'i=5' = 'i=30' , eval(newproc))

How can I encode to mp3?  Maple's AudioTools package only includes WAV file formats.  I would think by now Maple 15 would have included the mp3 format seeing that it is so standard. 

None-the-less, I feebly started to embark on what I thought would be a quick two step process - 1 - find the mathematics involved and 2 - code in Maple.  My searches brought me to some good information at www.mp3-tech.org ...
