There are some routines in Maple's library which, when called the first time, redefine themselves.

One plausible explanation for this is that the new versions are session dependent (external calls, say) while also more efficient to call (repeatedly).

For example, consider StringTools:-Join which seems typical of that package. First, consider it before it's been called at all.

> restart:
> showstat(StringTools:-Join);
 
StringTools:-Join := proc(...

Hi! I'm a Maple Newbie trying to use the Maple Training Videos.

They all work fine except for two, under Algebra: "Solving Equations" and "Working with Matrices". Both start OK, then die a few seconds in.

I'm using Kubuntu Linux, but I really don't think that that is the problem, since all the other videos work fine.

Could someone try these for me to verify if they work for you?

Thanks in advance for any help.

 

Hey.

If you go to url, http://www.fcet.staffs.ac.uk/blb1/FirstYearEng.html, you shall see four maple worksheets in XML format.

My issues is that i can open them all but the last one, Geometry?

Can any one suggest a reason why i keep getting an error when trying to open this sheet? Does it do if for you?

If i can be cheaky, If some one can open it, can they save it in a Maple worksheet and send it over to me please?

Thanks for any help

 

they seem to have disappeared!

Something strange happens when you try to plot this:

implicitplot([y = 1/18*(3*x+1)^2/x], x = 1/4 .. 1/2, y = 0..10);

If you change the y range so that it is, say 1, the wabbles in the function become smaller, but they are still their.

Why the wables?  I am using Maple 9.
 

I do not understand why

f1 := proc(m, S::set) map(s->`if`(s={1},{m}, s),S); end:

f1(X, {{1}, {2}}); differs from inlined version of the same

f2 := proc(m, S::set) option inline; map(s->`if`(s={1},{m}, s),S); end:

f2(X, {{1}, {2}}); The first non-inlined version f1 is be my opinion correct, but what about the inlined f2?

There are a number of facilities in Maple which may be extended. Included amongst those are `type`, `print`, `evalf`, and `latex`. The help-page ?extension_mechanism claims that all the built-in functions allow for extension. It also mentions a few system Library routines such as `verify` (but does not mention `latex`).

There are some descriptions of varying completeness in a few...

Searching for something completely different (it sounds almost like Monty Python), yesterday I stumbled over the conversion of trigonometric expressions to radicals, see ?convert,radical, and I became intrigued: would Maple be able to convert cos(2*Pi/17) to radicals? It was not.

Gauss was the first to show that the 17-gon could be constructed using compass and straightedge. The expression 16*cos(2*Pi/17) in terms of radicals can be found at the Wikipedia page Heptadecagon.

Hi

I have just filled up my motherboard with 2 Gb of RAM (from 512Mb) and installed a DVD re-writer to my aging Windows XP(SP2) machine.  It is now lovely and everything seems to work except my Maple 9.5 in Standard view which will no longer start (although in classic it does and seems to work).  I am in my final year at university and using maple heavliy for the final year project so I am relatively desparate at the moment.

Hi,

I need to work on the classical interface of maple11 on my MacBook Pro (Mac OSX 10.5).

Since Leopard is certified as fully UNIX compliant... I thought I could install this version on my laptop.

First of all, I couldn't see what was on the Maple11 for Linux CD, so I did :

 

sudo umount /volumes/<device name

 

then mount into a temporary directory

 

Consider the following:

> [seq](x -> i*x,i = 1..3);
                 [x -> i x, x -> i x, x -> i x]

Why does it not produce output identical to the following?

> [x -> x,x -> 2*x,x -> 3*x];
                  [x -> x, x -> 2 x, x -> 3 x]

i wish to know how to install my Maple 10 onto my laptop which uses Windows Vista.

Hi, folks. I don't have much experience with Maple. At the moment I am trying to get an idea how the underlying algorithms for polynomial root-finders compare. For example, I believe MATLAB creates the companion matrix for a polynomial to then solve for its roots (eigenvalues). NAG routines use the method of Laguerre. NETLIB routines use the Jenkins-Traub Algorithm. What is the underlying algorithm used by Maple to compute the roots of polynomials?

Hi community, Could you please shed some light on the algorithmic implementation of Local optimization library. I'm confused about the difference between Local Vs. Global Optimization in terms of the algorithms being used. Is it the same algorithms for L vs. G Opt. with an improved version of the same algorithm in the Global package. Or it is completely different algorithms.... Thanks in advance

I really like the new Maple 11 plotting features. But I have a problem with them, they use the comma (,) as the decimal separator and the period (.) as thousands separator. Normal (2d) output correctly use the period as decimal separator, though. Maple 10 plots worked correctly also. The machine OS is Windows XP Pro, and the system language is Spanish. I have checked that I have specified the desired separators in the language control Pannel. Could this problem be related to java language specification ? Does anyone know how could I change this behaviour ?
