Hey all,
I've been using Maple for a while, and for the most part, my scripts/procs have been pretty small, but they're steadily getting bigger. When they're too big to enter directly into a worksheet I use Vi which has worked great, but it'd still be nice if there was an editor designed to work a bit more closely with Maple.
Anyway, this summer I'll have some time off, and I was thinking about writing a language-aware editor for Maple. Is this something that you, as Maple users, would find useful? If there's enough interest, I'll probably start working on it next week. Also, if anyone's interested in contributing, I'll certainly be writing it in either GPL Qt (C++) or Java (MFC runetime characteristics probably aren't that important for an editor :) ).
Hello, I'm a PhD candidate student in Chemical Engineering.
My Lab is about to purchase a new computer. Our budget is about 3000-3500 Euros (~ 4000-4800 USD).
Our main research interests are Process Control and Optimization in Chemical Engineering. We rely heavily on Maple for symbolic calculations and Matlab for simulations and numerical calculations.
We already have a few P4's but they have proven inadequate for a number of tasks so we were thinking about purchasing a more powerful system. A cluster system has been one of the suggestions but we are not sure how to employ it, given that most of our code is designed to be linear (we are not programmers by profession, only by -informal- training). A friend (a software engineer) suggested a system with 4 dual core processors and lots of fast RAM as his best bet.
I recently got emailed a .sxc file. I did not know what that was, so off too Google I go, and find the site
fileinfo.net which lists lots of extensions. There I am enlightened: OpenOffice spreadsheet format.
But then I was curious. So I look up .ms, .mws, .mw and .nb. Results:
| .mw | Text | MacWrite Text Document |
| .mws | Audio | MWave DSP Synth Instrument Extract |
| .nb | Data | Mathematica Notebook |
No entry for .ms.
Why is this?
Regarding to Maple 10 Concurrent Network license.
Actually I have changed the static IP address for the licence holder of the Maple 10 network license. Thus I can't open maple worksheet anymore. Therefore how could I solve this problem?
I got spammed by Wolfram, touting their new
Mathematica 6. Being the curious person that I am, I went over to take a look.
First: their marketing material is slick. Very slick. It makes you think that they've invented some nifty new stuff -- until you look just a bit more and realize that some of it has been in Maple for ages. And some of these ideas were invented by Maplesoft, and yet Wolfram markets them better. Very devious - and I am sure will be very successful with a lot of customers!
Second: it's good. It looks like it warrants the major upgrade hoopla. The new features are very tightly integrated. I mean, in the case of Mathematica, the language and the user interface are now one-and-the-same. You can programmatically access the whole interface (live!), and you can use interface components in any program. This is going to give Maple 11 some serious competition.
Just a thought for my day...
In a system which, by default, evaluates the arguments of function calls it is little strange to make a habit of using an unevaluated function call as a data structure.
Passing around such an object may result in unwanted evaluation of the stored data.
Printing a worksheet made using the worksheet interface with input display set at Maple input I get really bad looking results when done from my Windows computers (Windows 2000 Professional, Windows XP Professional, and Windows XP Home). No problem from a Unix system I tried.
The printing of Maple input lines look the worst, but also headings 1-3 look bad.
The problem disappears if the bold font used for Maple input and headings are replaced by the corresponding non-bold.
I would like to know if this is a general problem, or if it is somehow related to the country specific settings.
In other words, does this happen on Windows computers in the US or Canada?
Can someone please explaint to me why this isn't working and some possible corrections. Any help would be greatly appreciated!
I'm trying to solve 2 equation and 2 unknowns. Below is the code that I have...

The (new) volatility index from the CBOE is computed from option prices
without using a specific model.
Understanding that as a special case one can derive a formula to get
higher moments from quoted prices in a completely model free way and
thus gets reasonable approximate values for mean, variance, skewness
and kurtosis without constructing an implicit density.
Besides interesting in its own these figures can serve for estimating
pricing models by providing initial guessing for parameters.
The Maple sheet shows, how to find the formula based on a result of
Carr and Madan.
Then the essential steps and procedures are given which allow to compile
I apologize if this has been addressed elsewhere on the site, but I was wondering if there have been any updates made for Maple 11 Windows Vista support. I am having an odd problem where, whenever I go to save or open a document in Classic Worksheet Mode the dialog box opens, and as soon as I move the mouse, Maple 11 closes completely. Any information or assistance would be greatly appreciated. Thanks a lot.

This sheet shows, how one can extract a "risk neutral density" from prices of traded options: theoretical
one can price options through a probability function (describing the stock's behavior) and if prices
would be given 'in a continuous way' one should recover that functions to get information on the stock
(differentiating prices twice w.r.t. strike).
The first step is a quite brute way: interpolate extracted volatility by a polynomial of low degree to get
the observable part of such an density. Now extend to the unobservable left and right tails by selecting
a Black-Scholes situation with reasonable parameters.
I find that reading lots of help pages causes eye strain. A way of reducing this that works for me is to change the background color of the help pages from white to yellow. This can be done by setting HelpBGColor=255,255,224 in the ini file.
On Windows XP the ini file will be found at C:\Documents and Settings\Joe User\maple9.ini or maple10.ini. For Maple 11, the file can be found at C:\Documents and Settings\Joe User\Local Settings\Application Data\Maple\11\maple.ini
Can anyone explain to me why the argument of the innerproc, which as y is a local of the outerproc, gets evaluated more than one level?
innerproc := proc(t)
print(t[1]); # or dismantle, or lprint
end proc:
outerproc := proc(x)
local y;
y := x;
print(y[1]); # or dismantle, or lprint
innerproc(y);
end proc:
outerproc(vector(1,['exp(0)']));

Hello.
This is not a question, but an answer. I have just installed Maple 11 under Ubuntu 7.04 Feisty Fawn and I thought I would share my experience.
1) Log in to an account with sudo rights.
2) Insert the Maple 11 cd for Linux. When asked about what to do with it, mount it.
3) Open a terminal and write
cd /cdrom
sudo sh ./installMapleLinux32
4) Enter your password.
5) For the location of the installation, I entered /usr/local/maple11 instead of the default.
6) After the installation (and the activation) is complete, I created two symbolic links as follows: on the terminal, write
Hello,
I would like to use Socket package to get informaction from HTML page on Website. COuld you help me please? I need to get the part of HTML file to use it in my procedure.
Thank you very much
