I recently came across a Probability and Statistics - Explorations with Maple book by Karian and Tanis.  It mentioned something about a stats package.

It seems that most of the stats package commands are mostly incorporated into newer maple versions. 

However some commands from the stats package seem to be better.  For example

Mean([x,3,1+x])  produces an error with the Statistics package in Maple where using Mean from the Stats package of Karian and Tanis produces a result. 

Hi, i am trying to find cosets of S_3 in Maple. I have done this so far: > restart; > with(group); > S_3 := permgroup(3, {[[1, 2]], [[1, 2, 3]], [[2, 3]], [[1, 3]], [[1, 3, 2]]}); permgroup(3, {[[1, 2]], [[1, 2, 3]], [[2, 3]], [[1, 3]], [[1, 3, 2]]}) > grouporder(S[3], ident); Error, (in group:-grouporder) expecting a permgroup or a grelgroup, but received S[3] > Group order should be 6 (which is 3!) but for some reason it does not work. Also I am getting an error message when I try to find cosets of S_3. > ident := permgroup*(3, {[]}); > cosets(S_3, ident);

If I highlight some text in the first line of a document and then wish to highlight text of the same color on the next line, and if the highlight color touches the one above in any way then a whole block is extended and highlighted for both lines.  

However it seems to be okay if different highlight colors are used.

I have developed a fairly complicated (by my standards) Maple routine that makes heavy use (again by my standards) of the numeric methods dverk78 and rkf45. Recently I posted about differences I seemed to be seeing between running this on Linux and on windows. I was in error; the difference seems to be between Maple 13 and Maple 11. Maple 13 gives the same answers on Linux and on Windows.

A favorite diversion of mine (and of many around the Maplesoft office) is xkcd. Its author, Randall Munroe, bills it as “a webcomic of romance, sarcasm, math, and language.” Since 2005, he’s been entertaining many self-proclaimed geeks with his unique and slightly skewed jokes on technology, computer science, mathematics, and relationships.

I really like the post in which a substitute teacher – hm, Mr. Munroe......

Does Maple 13 still have strange behaviours with empty sums like M12?

  #Sum(t^j*(z-a)^(-2*n+j)/j!,j = 0 .. -1+n); eval(%, n=1);
  #S:=Sum(t^j*(z-a)^(-2+j)/j!,j = 0 .. 0);
  S:=Sum(1,j = 0 .. 0);
  value(S);
  #subs(Sum = add, S); value(%);
  #eval(S, Sum = add);
  #eval(S, Sum = sum);

I have constructed a Maple routine which makes multiple calls to the dsolve numeric methods rkf45 and dverk78. I have been running on Windows Vista. Recently I began experimenting with Kubuntu Linux, thinking this might run faster. I was surprised to see that the same routine with the same numeric input gives different results depending on whether it is run on Kubuntu or Windows.

If I apply showstat to numtheory:-invphi I find that the last line is >remove(has,sort(map(convert,invrec(a,divlist),'`*`')),FAIL) What is invrec? >?invrec returns "no matches found". Thanks to anyone who can clear up this mystery for me! And why isn't it documented? So far as I can tell numtheory:-invphi works fine. --Edwin PS I am using Maple 13.0

Maple returns a message saying that the use of global parameters in
the dsolve command is deprecated and will be eliminated in future
versions of Maple. One should use the parameters option instead.

I find entering parameters that way a bit clunky and prefer to use a
function instead. Is there some good reason to use the parameters
option? See below for a simple example.

Here is a strange behavior. I can understand that an integer and its float could be considered different, but the behavior should be the same in or out of a list. In addition it should not depend on the number of trailing zeros. In addition it should not depend on whether the integer is zero or not.

Who has some insight on this, apparent bug in MultiSeries... The sqrt(2) answer is correct, not the 2.

Here is some statistics from the Cybernet Systems press release.

When exporting a maple page to PDF there's no way to tell where Maple will split the pages (where text ends on one page and begins on another).  Be nice to have a 'view split pages' options or something.

I find the zooming in on a plot rather cumbersome.  First you zoom and the plot tends to wander then you have to select the pan and zoom again. 

I would find it much better if you could make a box on the plot to zoom to.  Similar to one of AutoCAD's zooming options. 

Seems there's a little tweaking needed for the plot when parameters are left are out for two plots or more.  Maple doesn't take the plot far enough in some cases. 

For example:

plot([(1000^x),(x!)]);         With this format Maple doesn't, but should, include both plots.  It gets 'stuck' as it were on the x-axis going only to 10

however adding parameters fixes the issue, but I shouldn't have to do this. 

plot([(1000^x),(x!)],x=0..35,y=0..1e30);
