For some reason, whenever I make a 2D plot in Maple 11, the line always seems to be 'wobbly', not completely smooth like it should be. Does anyone know how to fix this? Thanks

I was mulling over an example that behaved differently when cut and pasted in a Document (2dmath input) and a Worksheet (1dmath maple input). The example was this,

M := Matrix([a]);
N := Matrix([b]);
(M.N)[1,1];
(M.N+N)[1, 1];

The last line of that, in Maple 11.00, produces the product of the list [1,1] and the addition M.N+N, instead of indexing into that sum's Matrix result as it does with 1dmath input.

Is that a bug? Clearly there are...

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.

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?

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... View 4496_instri.mw on MapleNet or Download 4496_instri.mw

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. Regards, Keenan

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)']));

I installed Maple 11 on two Macs yesterday. No problems (so far at least) on an Intel Mac. But on a G5 Mac, I have crashed the Mac 6 times in two days... more than the preceding month for sure, probably more than the preceding year... Before I contact support, I am interested in whether this is only me, or something general for PPC Macs. So, anyone using Maple 11 on a PPC Mac? [technical: Mac OS 10.4.9; PowerMac G5; one processor 1.6 GHz]

I am generally dissatisfied with poor quality plots in Maple obtained with implicitplot3d. In particular, I have a polynomial in three variables x,y,z with 84 terms of degrees ranging from 0 through 12 and with integer coefficients. I have tried using options grid=[np,np,np] with np=40 and higher, and numpoints=k, where k = 1000, 10,000, 100,000, or even 1,000,000: the edges are visibly not smooth even though the size of the .eps file grows considerably to some 3MB. Question: Any suggestions how to improve the quality of the plot? I say right away that I do not have parametrization for that surface - only an implicit definition. Perhaps I should try to find it.

1. When Maple exports its worksheet to LaTeX, it converts each plot to an .eps file with /drawborder set to true in the .eps file as a default. I have found no information or a preference in Maple 10 that would allow me to change that default to false. Is there a way to change that default in Maple to false? If not, is there a way in a TeX file later to change that switch to false so that .eps figures drawn with \includegraphics command would appear without a border? I know I can open any .eps file in say MS Notepad and manually edit the line /drawborder true to /drawborder false, but I am looking for a smarter way to do that.

In several comments on a post about a surprising failure of an attempted Maple calculation, subscripted names and indexed names are discussed as if somehow are naturally meant to go together. But the only reason that they are associated in Maple's Standard GUI's 2dmath is because Maplesoft chose to implement it this way. My own feeling is that subscripted names and indexed names should certainly not...

The omega shouldn't have been substituted into the omega[0] expression. Am I wrong?

So I've been all over these forums everyday since I got a new Vista laptop hoping to find a solution to the Maple/Vista issues. First it looked as if Maple simply would not work, then I found some metheds that dealt with changing certain appearance features before the install to get Maple to install, but the major complaint in all of this was the inability to open and save files. I finally got everything to work and want share the process with others. I posted this as a reply already, but felt that it warrented it's own thread since I'm probably not the only one looking for a concrete answer. The purpose here is to document a method that worked for me with an appropriate title so it can easily be found. Hopefully I'm not out of line in doing so, and hopefully this isn't a repost proving that I am a horrible searcher.:)
