Does anyone know what kind of algorithm Maple (e.g. version 12) uses for generating random samples by the means of Sample command

in the Statistics package?

Thanks a lot for every comment.

The SAE (Society of Automotive Engineers) World Congress is an annual event in April that draws automotive engineers from around the world to Detroit to learn about and share thoughts on new techniques and technologies. Once again this year, Maplesoft was an active participant. This was a milestone event for us as it was the first SAE Congress where we could show off and fully demonstrate the potential of the MapleSim/Maple solution. Even in these trying times in the auto industry, our corner remains vibrant and very optimistic about the future.  In no particular order, here are some highlights.

Something doesen't seem right, i use the code from the maple - visual basic example (from samples\OpenMaple\msvb ) of plotting a function.

with OpenMaple from VB, the function exp(x) has the asymptote at -infinity, under de OY

and with real Maple doesen't seem to have any problem, the plot looks OK.

who's fault is it and what can I do to improve the quality of the plots from VB - OpenMaple aplication

these are my results

While marketing material naturally talks about new features in a release, we of course also put considerable effort into investigating and correcting problems with the product. Many of these fixes are in direct response to problems reported on MaplePrimes.  Thank-you. We recognize that reporting these issues takes time, and we really appreciate your help in making our products better.

As a follow up to the original announcement, I thought I’d include a few more details on some of the new features in Maple 13 designed for engineers. For more information, visit the What’s New pages for professionals and for engineering education.

As a follow-up to the original post, I thought I’d mention a few of the additional new features particular to math education. For more information, visit the What’s New section of the website.

Concept Learning Tools: Maple 13 includes new and improved concept learning tools:

With the release of Maple 13, we have also released a major new feature to Maplesoft.com, Online Help:

Every one of Maple's help pages is now available online. With this new feature, you will be able to view the help pages right in your browser and download the source Maple worksheet to interact with in Maple.

We are pleased to announce that we have just released new versions of Maple and MapleSim!

Here are some highlights from the new releases:

Maple 13 includes completely new 3D plot facilities, which are faster and use less memory. Another nice benefit is you can now annotate 3-D plots just like you do 2-D plots, including proper math notation in titles and labels, tickmarks in multiples of pi, and arrows. You can also create fly-through animations, which zoom a virtual camera around your 3-D plots. We’ve put a few examples on our website…take a look.
 
Writing multithreaded applications is now a whole lot easier using a new task-based programming model. You no longer have to worry about synchronization tools – Maple handles that part.  For example, here’s an interactive Mandelbrot application that uses the task-based model to automatically distributes the calculations to all available processors.

And the in small-but-useful category, Maple 13 now includes an Export to PDF option.

For more information on these and many other features, see What’s New in Maple 13.

MapleSim 2 includes a really cool new 3D animation feature for multibody systems. You just define the model, and when you run the simulation, MapleSim automatically creates an animated version of your model so you can really see what is going on.  You can even attach your own STL shape files, so the animations look more realistic…take a look for yourselves!

MapleSim 2 also includes a results manager that lets you keep track of the results of different simulation runs. Previous results can be viewed without having to re-execute the simulation, and are accessible from one session to the next.

For details, see What’s New in MapleSim 2.

I don’t think anyone would argue that the last few years have been pretty eventful. Modern industry is facing critical challenges, as design tasks become increasingly complex. Fortunately, we are seeing the development of new technologies that are allowing us to rise to the challenge. Techniques like rapid plant modeling for control applications, robust formulation techniques for automatic model generation, and the application of symbolic computation technology are accelerating the modeling process while ensuring correctness and sound scientific principles. The world of engineering is changing, and I’ve been fortunate to watch some of these developments first-hand.

1/2 hour ago I got from Norton Antivirus:

I am running Maple 12 under vista.  All my programs begin with "restart" but each time I "restart" Maple goes off into never never land.  That damn circle that used to be an hour glass just spins and spins and when I hit the "stop" button, Maple asks if I want to disrupt a computation.  But there is no computation.  Have others experienced the same problem?   I can't run anything unless  avoid "restart"ing.              .....Edgar

I am not sure where is the proper place to report the following bug.

input:
version(); interface(version); kernelopts(version);
u[1] := proc (t) options operator, arrow; 1+2*t+3*t^2+4*t^3+t^4+t^5+t^6+t^7+t^8+t^9+t^10 end proc;
u[2] := proc (t) options operator, arrow; t end proc;
save u, "/home/user/test.txt";
restart; read "/home/user/test.txt";

output:
User Interface: 277223
         Kernel: 277223

Hey guys, I've had this problem for over a year already and I never took the time to resolve it.

On previous version of Maple, it was always very slow to load the help menu. Now in Maple 12, it freezes Maple completely.

What can I do to fix this?

Hi All,

I'm trying to use implicitplot to plot a function of two variables, x and y, with the additional constraint that x > y.

Is there any way to do this?  I have tried to use assume by the command assume(x-y, positive).

Maple recognizes the assumption, but when I try to plot with this assumption imposed it just won't plot (I get "Error, (in implicitplot) could not evaluate expression")

Any idea how to do this?  Is it possible?

Thanks,

JonasM
