It may be of interest to this community that the original Maple Project at the University of Waterloo was awarded the ACM SIGSAM Richard Dimick Jenks Memorial Prize in June, at the joint ISSAC/SNC 2011 conference (overlap with FCRC 2011).

See here for the announcement.

In 2010-2011, I persuaded tens of thousands of Russian and Ukrainian students and students in that Maple - a very useful thing.
Testimonials - the number of visits and thanks.
So I decided to resurrect some of my old sites.
Not just for history!

The first: Maple PoverTools.

A worksheet that plots Tupper's Self Referential Formula

The complexplot3d command can color by using (complex) argument for the hue, and compute height z by magnitude. So, when rotated to view the x-y plane straight on, it can provide a nice coloring of the argument of whatever complex-valued expression is being plotted.

Another way to obtain a similar plot is to use densityplot (with appropriate values for its scaletorange option) and apply argument to the expression or function being plotted. For some kinds of complex-valued...

The June edition of the IBM Ponder This website poses the following puzzle:

Assume that cars have a length of two units and that they are parked along the circumference of a circle whose length is 100 units, which is marked as 100 segments, each one exactly one unit long.

A car can park on any two adjacent free segments (i.e., it does not need any extra maneuvering space).

The problem

Back in 1996 I was working for the Symbolic Computation Group at the University of Waterloo, developing algorithms and code...

I would like to pay  attention  to the PhD thesis by John Baber in an actual field of complex analysis done with Maple: http://arxiv.org/PS_cache/arxiv/pdf/1106/1106.4737v1.pdf . It should be noticed that the usage of Maple is an essential tool of this work (for example, see p. 28, 43, and around), not a fashion trend.

Just wanted to let everyone know that there is a Maple 15 update available. Maple 15.01 provides:

• Enhancements to MapleCloud security settings
• Improvements to tools supporting multi-process programming on a local grid
• Extended MATLAB® connectivity to include MATLAB® R2011a
• Compatibility with MapleSim 5

To get this update, you can use Tools>Check for Updates from within Maple, or visit for ...

In a reply to Markiyan Hirnyk's recent question on this topic, Alec Mihailovs posted solutions 
for  n=1..7 for the mean distance between random points in an n-cube.

This is more of a blog entry, mostly a note to myself.

I wanted to generate a list of points on the surface of a deformed sphere. It turns out that Robert recently showed how to do that on a unit sphere.

Adapting his code is straightforward. So here is what I came up with. One proc generates the random points on the surface of the ellipsoid. Another proc generates...

A short remark. This would be a blog entry if those still existed.

I am comparing plot,options.

The style=point option has versatile options for symbols, their sizes, the number of points:

  , 'style' = point
  , 'numpoints' = 50 
  , 'symbol' = solidcircle
  , 'symbolsize' = 8

Hope the following statistics is of interest for the Maple community. Here are some data concerning the numbers of downloads of unlicensed copies from one of Russian torrents (see scrn1.doc , scrn2.doc , and scrn3.doc):
Maple 14 - 11.427
Mathematica 7 - 21.137.
In fact, the quantity for Mathematica 7 is  a...

The ability to color a 3D plot using a color function is geared more for functions of x and y only.

But quite often, the surface or pointwise 3D position of the plot is itself being specified as a height z which is a function of x and y. For the plot3d comand, that's pretty much the way it works (whether using an expression or a procedure).

So, of course, the very same rule that...

We have published an update to MaplePrimes today that addresses a number of reported issues with the site, and also introduces some new features.  Much of what has changed has been in direct response to your suggestions and feedback, and I sincereley thank you for that!  

Please note that we have plans to make other substantial changes in the not-too-distant future.  I have written in the past about improvements we want to make to search (including adding an advanced search feature...
