Hi everybody, I put on the Book pages of mapleprimes a way to implement functional objects with Maple. I'm deeply interested in your opinion about that... you can find my code here: View 744_indexed-output.mw on MapleNet or Download 744_indexed-output.mw

When mod(8,3) appears inside the subscript index it seems to take the value 8 instead of 2. Not sure what's going on: Correct bit: > modp(8,3); 2 wrong bit: > lambda[jj mod 3] $jj=0..8; > lambda[modp(jj,3)] $jj=0..8; > lambda[0], lambda[1], lambda[2], lambda[3], lambda[4], lambda[5], lambda[6], lambda[7], lambda[8] lambda[0], lambda[1], lambda[2], lambda[3], lambda[4], lambda[5], lambda[6], lambda[7], lambda[8]

Hello! I'm trying to install Maple 10 on my computer running Windows Vista Business N. However, the installation stalls at the point showing "Please wait, Maple 10 is being configured for your system. This may take a moment..." Nothing is happening after that. How can I install the software?

I find that if I start Maple10 and execute the following code, I typically end up with the warning. But if I re-execute the code once or twice again, the warning goes away and Maple evaluates the integral in terms of Elliptic functions. Great...but why should I have to re-execute the code a few times before getting a result?

A colleague was using NumericStatus to get information about the NumericEvents. But he noticed the following strange behaviour:

Hi! I'm having trouble with getting maple to calculate anything for me. Whenever I enter a calculation it tries to connect with the maple kernel but can't. I tried to look it up but all I found was firewall related stuff. This is not firewall related since I shut down my firewall and the same problem occurred. I'm running Maple 10.04 on Gentoo Linux with kernel 2.6.19-r2. Anyone know how to fix this?

I'm fairly new to Maple, so please correct me if I'm doing something incorrectly. However, I've uncovered some disturbing behaviour in how the Maple 10 engine finds the closed form of summations containing conditional statements. For example, consider the following statements: 1) sum(`if`(k=0,n,binomial(n,k)),k=0..n); => 2^n 2) n + sum(binomial(n,k),k=1..n) => n - 1 + 2^n The statements should be equivalent. However, Maple 10 returns an incorrect closed form for the first one. Similarly, define the following function: g:=(n,k)->`if`(k=0,n,n^2); g(3,0) + g(3,1) + g(3,2); => 21 g(3,0) + sum(g(3,x),x=1..2); => 21 sum(g(3,y),y=0..2) => 27

Maplesoft just announced the upcoming release of Maple 11. This new version of Maple will be publicly available in March of this year.

With this release, Maplesoft is taking everything that was great about Maple 10 and adding to it. Below I will list a few of the features that I am most excited about. If you wish to read the full list of new features please view this page.

The 2-D plotting in Maple 11 has been rewritten from the ground up. You will find that all of the plots coming out of this version are more attractive and much more flexible. The biggest improvement is that you can now include 2-D math in your plots as well as drawing directly onto the plot. You can finally include all math on plots that you can in the worksheet. As an example, you can now have your tickmarks set to a trigonometric scale and have markings ofPi/2,sqrt(x)/y^2,3*Pi/2 and so on.

You can also draw all sorts of shapes and objects onto your plots. So you can include arrows to point out important elements. Trace along your curves, or include descriptive text.

This is a new feature that could be very useful for professors or people giving presentations of Maple worksheets. This is a new view mode that turns every section in a Maple document into a slide. You can show these slides in a full screen mode that works the same as a PowerPoint presentation. And while you are in this mode you can still interact with your worksheet keeping the mathematics live and interactive.

Maple now allows you to choose different formatting modes for your mathematical output. You can just right click on any output and choose to change the Numeric Formatting for that result. This means that you can now have your numbers appear in Engineering, Scientific, Currency, Percentage or Custom formatting. Each formatting mode has a number of options that allow you to have your numbers appear exactly as you would like them to.

Maple now allows you to import data contained in Microsoft Excel files. This adds to the large number of file formats that Maple is able to work with.

 

Maple 11 has four new Mathematics packages built into it. These include Physics, Differential Geometry, Differential Equations and Graph Theory. As a Computer Science graduate I am most excited about the Graph Theory package. This includes all of the tools that you need to solve most Graph Theory problems. If I had this package during my time in university, my life would have been a lot easier.

 

 

 

I've had several problems with my Maple installation on my Dell labtop with Xp Pro, sp2, 2GHz Dual core, and 1024 ram. When the AC-adapter is plugged in it works like a charm, but when it only runs on battery, it will not operate to its best! It slows down, and chokes on all operations. I have problems while scrolling down on the page, and everytime any item is selected. I have tried several things in the option menu, but none seem to work.. Maybe the wrong combination. The battery setting of my computer is working at optimal. I have tried with setting it to full speed and all the settings on the full scale.. Still no good.

HELP!! I've just installed more memory on my iBook..it now has 1.5Gb. I tried starting Maple10 and no response. The Maple10 icon just "bounces" in the Dock like any other app about to start then nothing, not even the splash screen. Maple 10 was working fine (but slow) with 512Mb.

How does one assign from a solution set? In the following example, I would like to get the square roots of b and c where when solved, b=9 and c=10. How does one assigned the values obtained in the solution to be able to manipulate them later? Thanks. > `πx`^2 = `kπ`(y^2-x^2); print(`πx`^2 = `kπ`(y^2-x^2)); 2 / 2 2\ πx = kπ\y - x / > `kπ`(y^2-x^2) = Pi(z^2-y^2); print(`kπ`(y^2-x^2) = Pi(z^2-y^2)); / 2 2\ / 2 2\ kπ\y - x / = Pi\z - y / > `πx`^2 = `kπ`(z^2-y^2);

I am attempting to do some game theory models for the collectible card game Legend of the Five Rings (www.l5r.com). The problem I am having is Polymorphisms, Inheritance, and Constructors in Maple 10. The game consists of several Card Types, each with distinct characteristics. I want to define a construtor module called CARD. It will have a TITLE and along with procedures getTitle() and setTitle(String). I then want to have a constructor module called HOLDING that is a CARD and has all the characteristic and procedures of CARD, but also a variable GOLDPRODUTION and procedures getGoldProduction and setGoldProduction.

I am trying to create my own package (module). I have read a lot helps in Maple and search this forum. But I don't know why this doesnt work 1. There is no file in /home/rno/math/maple/lib/ rno@amd:~/tmp> ls -l /home/rno/math/maple/lib/ razem 0 (it is in polish; it means there is no file) 2. The Maple script look like this: rno@amd:~/tmp> cat convacc.mp MyModule := module() export f1, f2, f3; local loc1; option package; description "Ala ma kota"; f1 := proc() eval(loc1); end proc; f2 := proc( v ) loc1 := v; end proc;

I have just bought a new labtop computer... A fujitsu siemens. With 1.6 Dual core, 512 MB ram and Windows XP pro. At my university we are handed out the cd's for selfinstallation, but this time it doesn't seem to work. My errors are InvocationTargetException errors, even before installation begins. I have searched the internet empty for solutions, but none have seemed to help. The same problem was encountered by rhorrox, see: http://www.mapleprimes.com/forum/maple-10-failing-on-install I have therefore tried different medias, I have burned the iso-image, this is what were handed out, and tried installing from a cd. I have also tried mounting the iso via Daemon tools. Both with the same errors.

The appearance of this thread has degraded over the years, but most all post about the MRB constant can be found by entering "MRB constant" into the search box.
