MaplePrimes Commons General Technical Discussions

The primary forum for technical discussions.

The list of the GUI problems is long, so I'll just summarize some of them.

In text groups, when the writing cursor is moved, the cursor is often not visible at the new position (where it actuall knows it is at), but often remains visible in a trail of places where it previously was.

In Help, the first letter of the search word is usually missing so that it is necessary to start with a space. Also in Help, both the scroll bar and the actual search...

My system: Windows 8 x64, Maple 17.01 x64.

After launching Maple we have a process maple.exe (C:\Program Files\Maple 17\jre\bin\maple.exe) that consumes approximately 80MB.

We run the following piece of code:

>restart;
>for i to 1000 do
>factorial(300);
>end do;

After running for the first time of this code the process maple.exe consumes 100.5MB
After second running of this code the process maple.exe consumes 111.6MB
third running --- 122.4MB

I am pretty new to programming in Maple and trying to learn the language. One thing I needed was how to handle lists in a specific way. I have used many hours on this issue now and even asked questions in the Questions section. Other users helped me with clever tricks and I am grateful for that. What is left is however a feeling that one need to know a lot of rather Ad Hoc commands to accomplish your tasks. I looked for operations in the ListTools package, going through all...

Let d be the Feigenbaum delta constant 4.66920160910299067185320382046620161..., a be the Feigenbaum alpha constant 2.50290787509589282228390287321821578... and m be the MRB constant 0.18785964246206712024851793405427323....

d*m - 2 (600 a - 2537)/(5 a - 2373) = 9.232940534412995...*10^-19

or you could write

1/10*(d*m + 564446/(2373 - 5 a)) - 24 = 9.232940534412995...*10^-20

I'm fairly sure I discovered a bug with the Maple 17 Calculus Integration tutor.

I was working on int((x^2+2*x)*cos(x), x);.

The first step that the tutor wants you to do is to rewrite the integral by factoring out an x from the first term, and changing cos(x) to -sin(x).

The next step is to rewrite it again, this time changing sin to cos, making the intergal  -x(x+2)cos(x)

Next, the tutor distributes the X again, making the integral -(x^2+2*x...

The latest Maple 17 bashing from Mathematica appears on their comparison webpage.

The first thing that paid my attention in their "comparison" was their comparison of the Mobius project to the Mathematica demonstrations project.  To my knowledge the Mobius project is an extension to application center which I thought was the same as Mathematica demonstration project anyways ???

Anyways anyone have thoughts on this recent comparison?

I've been playing around with power towers and thought my latest might be interesting enough to post.

I used Wolfram Alpha on the big numbers (n=5..50). Some corrected.

What do you think about spliting of single worksheet where code and results are placed into two separate worksheets where code and results of computation are placed separately?

Thank you.

At some point a version of the Maple Player (for the PC, rather than iPad) became available for download from its webpage.

Try to run the following:

>restart;
>d := conjugate(u)*conjugate(y)+conjugate(v)*conjugate(x);
>z := conjugate(f)/d+conjugate(G)*w*conjugate(w)*conjugate(y)/d;
>z2 := simplify(z);

and you will get correct answer

Everyone knows that Maple combines a smart user interface with a highly sophisticated mathematical engine, where common tasks are performed quickly and seamlessly with point, click and drag operations. Of equal importance, however, is the fact that Maple is also backed by a comprehensive programming language. Also called "Maple", this language combines elements from procedural languages (like C), functional languages (like Lisp) as well as object oriented languages (like C++...

A few weeks ago, we announced that we had established a partnership with DigiArea, Inc. to bring the Maple IDE to the Maplesoft Web Store.  Development is progressing well, and I'm happy to report that we expect to have the IDE available for download beginning on June 19th.  



On May 17, 2013 I finished a 2,000,000 or more digit computation of the MRB constant, using only around 10GB of RAM. It took 37 days 5 hours 6 minutes 47.1870579 seconds. You can write marvin@marvinrayburns.com for the digits.
The program I used was based on Richard E. Crandall's work:
Richard E. Crandall,Unified algorithms for polylogarithm, L-series, and zeta variants(53 pages)

Last week we added a new feature to MaplePrimes that provides the ability to sort the answers to a question by votes (default setting), or by date. Based on a few of your suggestions to that post, we have enhanced this feature today.

First, you now will notice that there are three options for sorting:

  • Sort by votes
  • Sort by date (oldest first)
  • Sort by date (newest first)
