On the MKM list (Mathematical Knowledge Management), I just read about a very interesting initiative by chemists. A publisher is doing semantic markup of their data. As the poster on the MKM list noted, it is rather sad that it is chemists that are leading here. Mathematicians gave it a half-hearted try (see the mostly defunct OpenMath or the highly-hyped but mostly ignored MathML). But this is probably because semantics of mathematics is so incredibly hard! The efforts in OpenMath and MathML in that direction were really lame, which probably contributed to their uneffectiveness. It is also why the QED Project went nowhere.

Hello: I have abstracted out an issue I am having using dsolve in the context of sqrt functions. Basic Problem: I am attempting to solve a a simple ODE with a piecewise continuous RHS. The RHS has a sqrt function. This simple problem in the form we have gives an error. We make a couple of other attempts to simplify this manually - in its most simplified form it seems to not given any error message. However, even then, the piecewise continuous RHS is not captured properly in the numerical solution. Can somebody help explain/solve the problem? Thanks. (NOTE: PLEASE IGNORE THE FIRST LINE OF THE MAPLE WORKSHEET - I DO NOT SEE IT IN THE MAPLE FILE, BUT IT APPEARS ON THE LINKED SHEET SOMEHOW!)

Official History, as written by the authors [later Maplesoft versions were somewhat embelished]. More interesting still is the full list of releases until Maple 9. Actually, that is missing V release 5.1. Counting 5.1, 9.5, 10 and 11, "Maple 11" really ought to be named Maple 26. How many pieces of (commercial!) software have had 26 releases in their lifetime, and still going strong?

I have been having trouble with the riemanntheta function included ith the algcurves package. I am running Maple 10 on a MacPro under Mac OS X. There are two sorts of trouble: 1. Memory leaks: repeatedly calling the function eventually uses up all of my memory 2. Incorrect results: Maple's values are _sometimes_ incorrect; for example, a large value at a known zero of the function. Anyone else run into this? TIA.

Hello, I need to create a picture in eps format to use it in LaTex Document. I use plotsetup to create it but the output is not worked corretly. In Maple 8 it workes. plotsetup(ps,plotoutput=`plot.ps`,plotoptions=`portrait,noborder`); and then I use some plot command. I am not able to compile the maple output in LaTexPdf. I try to open it in CorelDraw and it is opened, but I am not able to work with it like I am able with Maple 8 output. Why? Is it different format of eps? Could you help me please? How could I create eps file to use in LaTeX? Thank you very much. Vladimir

When execute the following worksheet to "Export" command, Maple lose connection to kernell.

It's possible to integrate a whole mapleworksheet in MapleTA. I made some fully randomized statistical questions in MapleTA. The calculations will be done in a MapleWorksheet and stored in a list. The MapleTA application only presents the output from this mapleworksheet by reading this list. Please download this questionbank from http://www.maplesoft.com/applications/app_center_view.aspx?AID=2062).

Hello, i'm newbie here and spanish... Someone can help my, i want an procedure/function that you put an matrix and it will give you the rang/rank but not using the function implemented un maple... I'm using MAPLE 10 THX

Open a worksheet in document model, and input the next line in math model plot(x^2,x=-1..1,title="title"); and it will show a plot. Now select "title" in the quotation marks (not include quotation marks), type in "aabb" (not include quotation marks) and press enter, there will be an error. But if you select "title" including quotation marks, and change to "aabb" (including quotation marks), there will no problem.

The following seems like a bug. Now, it could be that Logic is not built to handle such requests, in which case it should die gracefully, instead of giving funny answers.

> Logic[BooleanSimplify]((x > 3) &and ¬ (y > 5) &or (y > 5));

                (5 < y) &or ((3 < x) &and ¬(5 < y))

and yet

> Logic[BooleanSimplify](a &and ¬ b &or b);

                               a &or b

This one asks for something trickier, and more difficult to ask for. If you are not quite sure where to post, then you should put it in the wish list. Here, you should document use cases for Maple (the complete system) which should 'just work', but for some reason doesn't. What is a use case? It is a description of a task that needs to be done, which should be a straightforward application of Maple. It belongs here if it turns out that it is not straightforward (or worse). The bulk of the posts should be about those task descriptions. Suggested solutions should, in most cases, be omitted. This is where we should put our trust in the developers to come up with a good way to solve the problem, rather than to try to micro-manage.

Please use replies to this blog post for free-form wish list items for Maple 12. Anything you'd like to see, in any part of Maple, go for it.

It's time for maple users here to really start thinking about Maple 12. What, you say, Maple 11 just came out, I barely know what's in it, give me some time! Well, no. Think about it: what are the developers doing? They are most certainly sitting idle. They finished Maple 11 some time back, so starting some time ago, they started planning Maple 12. So if mapleprimes users are quick enough, they might still be able to influence what goes into Maple 12. Ok, there are really two methods to go about asking for Maple 12 features:

This workshop is a part of Calculemus 2007, Hagenberg, Austria.

The intent of this workshop is to examine more closely the intersection between programming languages and mechanized mathematics systems (MMS). By MMS, we understand computer algebra systems (CAS), [automated] theorem provers (TP/ATP), all heading towards the development of fully unified systems (the MMS), sometimes also called universal mathematical assistant systems (MAS) (see Calculemus 2007).

Just came across and interesting blog post on language design, focusing on the architecture versus features dimension. Trying to place Maple on this, it pretty much has to co-exist with Perl in the Pragmatic column. For comparisons' sake, one would have to place Mathematica in the Consistent column. The arrow of time graph is quite interesting. Maple is firmly a 'mature platform'. Whether it is 'bloated' is a very subjective call at this point; people of a more minimalist bent would certainly say so, but compared to something like Perl or C++, it most definitely is not. However, it is rather inevitable that it will become bloated: Maplesoft needs to push out new versions for people to upgrade to, and to be able to sell those, 'new' features have to be there to warrant an upgrade, right?
