I have data organized in a Matrix from which I want to select a sample based on a certain (simple) criterion, e.g. no cell in the first column to be negative.

I was quickly able to find a way to do it, inspired by a method Preben Alsholm used in a recent mapleprimes post.

But, I wondered, is that the most natural approach? So I quickly found another approach and compared them.

Any other suggestions welcome. Particularly methods that could...

We are looking for someone that can develop some maple scripts for us. Must have some chemical engineering knowledge.

The following is the matter of so-called central limit theorems. We have the sum of random variables S:= ksi[1] + ksi[2] + .. ksi[n]. We know only that the number n is large, the variables are independent or weakly dependent, and each ksi[j] is small with respect to S in a certain sense.

By the  central limit theorems it implies that S is close to the normal distribution.

Here is the procedure which illustrates the Lindeberg-Levi theorem ( see

For pass argument I use the ssystem command.

So I'm able to pass argument by launching my script like this.

login@hostname:  echo  ARG | ./example.mpl

example.mpl look like this:

-------------example.mpl----------------

#!/usr/bin/maple
with(StringTools):
ResultArray:=ssystem("read MapleArg; echo ${MapleArg}"):

Maple 15, Windows7x64, Standard v. Classic

I have noticed that, on my system, the smoothness of some INLINE plots is better in Classic than in Standard. Is this some regression or some installation-specific quirck I wonder?

In Tools->Options, I have plot anti-aliasing enabled (whatever that is).

This looks alright in Classic

plots:-implicitplot(
  [ x^2 + y^2 = 1, x^2 + y^2 = 2 ]
  , x = -2 .. 2
  , y = -2 .. 2

The folks at Grand Valley State University have posted a nice set of Maple tutorial videos on YouTube.  The videos have been designed for students taking 200-level math courses, but they are certainly suitable for anyone who is either new to Maple, or looking for a refresher.

Enjoy!

Not in the same league as the "Mandelbulb" pictures you may be referrng to, but a couple of years ago I messed around with plotting 3D Quaternions in Maple. Pictures in the attached worksheet

I've submitted an application to the Application Center: Great Expectations.  This is an interactive Maple document, suitable for instructional use in an undergraduate course in Probability.  The mathematical content is related to the Laws of Large Numbers and Central
Limit Theorem.  It requires no knowledge of Maple to use.

I'm happy to announce that, having retired from University of British Columbia, I've joined Maplesoft as a Content Developer.  Some of my work will be appearing in the Application Center from time to time, and I'll announce them here.  If you have any suggestions for topics you'd like to see in the Application Center, I'd be interested in seeing them.

The iPad is a very exciting device and it has been gaining broad adoption from our academic and professional customers alike. It was a logical step for us to bring Maple technology to this platform.
 
The Maple Player for iPad is now available in the Apple App Store. It comes bundled with ready-made interactive Maple documents, covering topics like integration, differentiation, computing...

Syrup-0.1.8.zip is a rewrite of the Syrup package, an electric circuit solver for Maple.  It reads either a SPICE-like syntax, or a compact ladder notation.This update runs on Maple 15. I've added a few features, such as the ability to export to Modelica, which can be used with the ?MapleSim product.  Also added are two new controls,

No, I'm willing to bet it's about as random as flipping a coin.  You might say, huh?!  I think my theory is interesting but this isn't really a maple question although perhaps we can make it into one, it would be that much more interesting.  I haven't done so yet, but anyone is welcome to.

With practice, I can flip a coin and get 30 heads in a row no problems.  Now say for a roulette wheel operator who uses it constantly, you don't think he's gained...

I have uploaded to the Maplesoft Application Center a worksheet exploring the orbital dynamics of the recently discovered Kepler 16 system, where a planet orbits a double star. 

Your comments and suggestions will be appreciated.

 I would like to pay attention to the article "Exploratory Experimentation and Computation" by David H. Bailey and Jonathan M. Borwein just published in Notices of AMS, 2011, V. 58, N 10, 1410-1419
 ( http://www.ams.org/notices/201110/rtx111001410p.pdf ) . It should be noted that Maple is one of the leading characters of this article.

I was digging through my old worksheets and came across something I created for one of my projects I never finished or well am still intending to work on.  Anyways I had come across a plot created in Matlab and noticed Maple didn't have an option to create gridlines in the axis on a 3d plot like Matlab did (at least I think it was Matlab) in any case I tried to mimic the same thing in Maple as exactly as I could.  The below is the groundwork I came up with and I...
