### Generating an Array of Random Floats

February 11 2007 by Maple

While numerically testing a solution for the February 2007 IBM Ponder This challenge I had to generate a large n×2 Array of random floats uniformly distributed in [0,1).

I am trying to create an array for testing the FFT errors within maple. Every time I try to assign values to the 1024-element array, the program prints them all out. Is there any way to turn this off?

### Statistical Tests - Urgent!!!

Hi,

I have posted the topic once, but as recieved no reply, I am trying a little force, hope it ain't forbidden:-)

Ok, basing on Carl-Rubin theorem, it is easy to determine UMP test for testing H0: p<p1 or p2<p vs H1: p1<p<p2 where p1 and p2 are given probabilities. To test this at some significance level alpha, we repeat a Bernoulli scheme B(p) n times. In fact, for us to obtain a UMP test for H0 at the level alpha, we have to construct a randomized test, based on a statistic S being the number of successes. If S falls between x_a and x_b we decide to reject the Null Hypothesis. If S happens to be x_a or x_b, then we run another experiment and basing on its result we reject or accept H0.

### Testin Statistical Hypotheses

Hi there, I've just started using Maple, and must say it is a real good tool - powerfull!!! But to the point, I have created a 'simple' procedure for determinig the shape of UMP Unbiased test for testing H0: the probability 'p' of getting "1" in the Bernoulli scheme is

### MapleV, an Emacs Mode for Maple

Because my ISP no longer offers home pages, I'm putting the source to maplev-mode here.

maplev-mode is an Emacs major mode for developing Maple code. Its features include:

• font-lock (highlighting) of Maple keywords
• automatic indentation
• syntax checking (via Mint)
• online Maple help
• online display of Maple procedures
• auto-fill support

It works properly with NTEmacs on a Windows machine and with GNU Emacs on a Linux box. It has been tested with GNU Emacs 21.2. It is supposed to work with Xemacs but the testing done with Xemacs has been minimal. The manual is badly out of date.

The current version supports Maple 11 and previous releases of Maple.

### testing equivalence of relations

Hello, my question is connected to the topic in my blogpost - Testing objects for equivalence. Alec Mihailovs wrote a procedure for nested verifications. But this doesn't work for relations where one relation equals to the second one multiplied by a constant. They are different, but solution is the same. For example: x=1 2*x=2 also Maple answers false. verify(x=1, 2*x=2,relation); false

### Maple Used to Develop Innovative technology...

Maplesoft.com recently posted a new user story that describes how Maple was used by a German company that develops, produces, and distributes towing kite wind propulsion systems for modern means of sea travel and transportation.

Here is a quote from the company:

“SkySails is grateful to Maplesoft, because Maple saved us a lot of time. Using Maple was very easy and quick. The computations we used are probably very basic for Maple, but they were extremely effective for SkySails. When testing the simulator, the correctness of the mathematical model is crucial. With Maple, there was nothing to worry about!”

As a project I have found need to create a new type through the external calling interface of maple. To allow for easy use of this type I have been overloading the operators to handle this new type. Most of them seem to work quite well but I am having a problem that by overloading these operators some totally unrelated functions seem to break (even when not dealing with my new type).

### Help with algorithm...

This is my first post here... My algorithm is about the 3x+1 problem. I want to test if some types of numbers have a stoping time. Until now i managed to do it by just testing one type of number each time... So i would like to automate the proccess... Here is an example: > k := 16 n + 3 > while modp(k, 2) = 0 or modp(k, 2) = 1 do if modp(k, 2) = 1 then k:= (3n+1)/2 elif modp(k,2)=0 then k:=k/2 end do k Well this example will produce k= 9n+2, which is smaller than the original 16n+3 so I know that numbers of the form 16n+3 have a finite stoping time...So it passes my test. If for example i start with k:=16n+7 i will get k=27n+3 which is bigger than 16n+7 so i do not know if this number has a stoping time... so it ''fails'' my test. I hope this is clear to you.

### Testing objects for equivalence

UPDATE!!! I found that my blogpost appers in Maple reporter. You should know, that this blogpost was just a question about how to solve my problem better. Alec Mihailovs gave me and aswer and his solution of testing nested objects is much better. If you still want to use my piece of code, you should remove "set object" form "convertAMVStolist" procedure and replace all occurrences of "hastype" with "type" (as mentioned in comments below).

This piece of code should be able to test two objects (not of every type) for equivalence (like testeq() does). The benefit is, that it should be able to test also nested objects. Is there any other and more simple way how to do that? How to test nested objects in sets?

### running maple with the -P parameter

October 10 2006 by Maple

Hello, I would like to use Maple for testing the syntax. In documentation is mentioned the -P parameter, which switch the maple into syntax checking mode, where none expressions are evaluated. I can imagine, that I will run maple with -P parameter to process a worksheet and after proceeding, I will search the errors in output. But I would like to have one Maple instance still running and to send/receive data continously. That means to sent through the one pipe to maple some expression and through other pipe receive answer from maple. Is it possible? Can you write here some solution using python or perl?

### MaplePrimes: Member Profiles

I joined MaplePrimes three short days ago and already feel very enthusiastic about all it has to offer. Just yesterday, I introduced myself in my first blog post. Much to my amazement, my post was read over 150 times in the first 24 hours, which is more traffic than my home page sees in weeks—what a great website! I have some questions and suggestions concerning MaplePrimes member profiles:

### Need suggestions for a new Maple package...

I'm working on a Maple package for computing in multivariate polynomial quotient rings, ie: rings of the form k[x1,...,xn]/I where k is a field and I is an ideal of k[x1,...,xn]. I currently have commands for the following:
• computing inverses
• exact polynomial division
• simplifying fractions to a minimal canonical form
• testing whether something is a zero divisor
• testing whether the domain is a field or an integral domain
• testing whether something is a unit, or whether two elements are associate
• compute a basis of monomials for the quotient ring as a vector space

Last week, Maplesoft exhibited at NI Week in Austin, Texas, the primary conference for the National Instruments (NI) user community. They are best known for their data acquisition and testing hardware. More recently, through their software product LabVIEW, they have been becoming significant in the general modeling and simulation space.
