Anyone?  Can anyone show a simple worksheet to show Maple doing some cluster analysis?

A while ago I got stuck in trying to attempt this with Maple, time was scarce and I've let it fall into the dust where it has laid since.  I am reviving the question as I was reviewing some older posts. 

Lack of answers after a certain period of time could also mean people just don't find it fun to backtrack on this mapleprimes site.  However it's just a thought. 

It would be similar to the Mathematica cluster analysis on 2d plots (and I do not know Mathematica at all).  Translator in Maple doesn't work well but if someone could translate it or make something similar in Maple that would be helpful. 

So it would be similar to observing the stresses on a spanning bridge and compressions in the supporting columns.

@Alex Smith  hopefully I wasn't inadvertantly implying that one should wait for Maple 15 to solve.  I was only replying to his question as to when Maple 15 would be released, nothing more and nothing less.

Referring to Alec's comment for cryptography packages, that would be cool.  I am a little bit dissapointed in the descriptions Maple gives for topics related to cryptography ie. the Index of Coincidence and Kasiski test, the amount of information is a little sparse. 

Better error detection - In a proc sometimes one forgets a colon or semicolon on a line which causes an error, I think Maple should be able to pick out the missing culprit (although maybe it's harder to pick out  than I think) one usually gets the error - invalid use of a name.

Anything you can manipulate with a mouse after a calculation is performed there should be an equivalent coding command available that can be setup in the command line ie.-  adjusting the size of a window a plot is displayed in, adjusting the frames per second in an animation

To be able to browse more than one large matrix/array at a time.  If one large array/matrix browse window is open, one cannot open a second without first closing the first.

Double click zooming for plots - If I couble click on a spot, I want Maple to auto zoom a certain magnification (possibly user adjustable) to that spot.  Currently it only zooms from the center of the view.

New versions are now released in the beginning of a following year.  Based on passed release dates Maple 15 should be released sometime around April/May 2011.

Thanks.  Okay I think I see now why unapply had to be used -- from the unapply help : Use the unapply command when constructing an operator using contents of variables or evaluated expressions.

I was using Maple 12 so maybe that is why it didn't work so well.  I went for dinner after starting the export of the gif, came back (20 minutes later) and it seemed to have done nothing, although it did start.  I also probably have a slow computer by todays standards.  It's only a single core machine 4 or 5 years old now.

Your problem was not using the arrow operator

Grawlixes?  Never really thought of it like that before but now that it's mentioned, every time I look at the logo it will be a passing thought.

So then an infomative poll should be conducted here on Mapleprimes then for some more insight?

but ... alas polling was an option on the old mapleprimes and no such thing exists here on the new mapleprimes. 

Thanks, yes that is what I was looking for.  Commenting isn't working right now so this will have to be an answer

I was thinking I could use a % or \ character on my user variables to call them from inside the string.  So the ParseTime line would look something like this instead

  StringTools:-ParseTime("%Y-%m-%d","%Year-%Month-%Day_^")

Very sorry, as a much needed example.

how about this

WhatDay:=proc(Year::string)
  StringTools:-ParseTime("%Y-%m-%d",Year)_{'weekDayName'}
end proc:

WhatDay("2007-02-13")
                                       "Tuesday"

Now I wanted to write the proc without using the Year::string? I'm going to guess it's either a bad idea or it can't be done. but something like...

WhatDay(Year,Month,Day)
  StringTools:-ParseTime("%Y-%m-%d", ??? )
end proc:

The ??? needs to be in a string but I'm not sure how the variables can be called from the proc from within the string. I couldn't figure it out. Can it be done?
