If one has ever used an XML editor, one knows the frustration of you having to do the bulk of the work locating mismatched or unclosed <> tags. Let us view tags as delimiters on sets and subsets. Consider the case where the XML editor has checked all beginning and ending tags and found an equal number of beginning and endint tags of a given name: a, b, etc. Nevertheless, even though we have an equal number of and tags and and tags is wrong syntactically because the "set" "intersects" with the "set" non-trivially, yet neither set is a proper subset of the other. Certainly, if a computer algebra system such as Maple can determine set overlaps like this, then

MapleTA currently restricts feedback in only one sense -- you can prevent access to feedback until AFTER a specified date. I provide MapleTA support for the University of Nebraska-Lincoln, and an instructor has come to me with what seems like a reasonable desire -- that unfortunately does not seem possible at this point. He is creating proctored exams. Students take proctored exams on campus in our testing center, which is staffed by proctors. The instructor wants his students to view the results of their exams in this proctored setting so that they can mentally take note of which questions they got wrong and which questions they got right, but cannot produce a hard copy of the exam. And he doesn't want students to be able to go back to their dorm rooms and view the exam.

I was just wondering what a good book to learn engineering related mathematics with maple would be? There's one on the website of maplesoft but 125 seems a lot to pay for a book I'll use just for fun. So do you guys have any suggestions? Thnaks

This is a long shot, but I think Maplesoft should open up its bug database and allow MaplePrimes users to vote up or down on bugs, reddit style. This would provide direct feedback about which bugs really affect people. Behind the scenes you could cross-reference the votes with account data to get all kinds of useful information: like what bugs disproportionally affect new users, or what bugs annoy experienced Maple users the most, etc. This would allow you to focus attention...

Why not put the entire Maple help-system online? I mean, as html. No served .mw or plugins. No huge .pdf downloads. Just the goods, one page per routine, that load and render fast for every half-decent browser. No registration and login would be nice too. Consider the competition's sites, here and here. Wouldn't that be another...

Hello. I wanted to report problem with installation of Maple1102LinuxUpgrade.bin in Gentoo Linux. My attempts to install it failed with the following error: peter@camobap ~/tmp $ ./Maple1102LinuxUpgrade.bin Preparing to install... Extracting the JRE from the installer archive... Unpacking the JRE... Extracting the installation resources from the installer archive... Configuring the installer for this system's environment... Launching installer... * run-java-tool was invoked directly * run-java-tool should only be used via symlinks to it And with more debugging we see:

At present, there seems to be no way to generate a plot and then export it under program control. One solution to this, which could be implemented in under an hour, is a new command plottools:-export. This would provide a program interface to the functionality that is currently available by right-clicking on a plot and then selecting “Export”. Relatedly, a simple way to get a plot into ImageTools (and to do this under program control) would enhance Maple's graphics capabilities. The cost/benefit ratio for this seems to be extremely strong.

It's nice that the plot command tries to warn the users about incorrect inputs: [> plot(sin, x=4..6); Error, (in plot) invalid plotting of procedures, perhaps you mean plot(sin, 4 .. 6) [> plot([cos,sin], x=4..6); Error, (in plot) invalid plotting of procedures, perhaps you mean plot([cos, sin], 4 .. 6) However, there is a shortcoming that I suggest should be fixed: These lines produce a warning and an incorrect plot [> plot([cos,sin(x)], 4..6); [> plot([cos(x),sin], 4..6); [> plot([cos(x),sin(x)], 4..6); Whereas these lines produce no warning and an incorrect plot

My apologies if this has been posted before, but a quick search didn't turn it up. I'd like to have a simple, "clickable" way, preferably in the "PlotBuilder", to shade in the region *between* two 2D curves or two 3D surfaces. I know that there are packages to do this, but I'd like my students to be able to do it without learning any new commands or loading any new packages --- it's just too useful when you are teaching calculus. Thanks for listening! ----Josh

I was recently asked what I thought of using Approximate Entropy in financial trading. I was not much familiar with ApEn; so I experimented a little. A natural thing to do is consider long bit strings that are suspected of being able to (but not known to) pass general tests for randomness. Examples include leading bits of Pi, sqrt(2), etc. So I began with the following. PiFive:=evalf[350000](Pi): bits:=convert(PiFive,binary,1000000): (Such things are helpful in various applications, not just studying ApEn.)

Maple currently cannot output graphics as pdf. It would be convenient for me (and anyone else who uses pdf(la)tex) to have this facility rather than converting the .eps output to pdf before inserting into a tex document. Thanks Mark

On the ground of problems with tab indentation, see my former thread, I now instead use spaces as indentation (as I suppose the majority of you do too, or what?) Using spaces comes at a price, though: Each indentation of mine consists of three spaces. For deeper nested/indented structures of code these, I think, becomes quite tedious to enter. Therefore, the following question: When using Shift + Enter, that is, creating a new line, is there some way to tweak Maple to automatically position the curs

I could not find any place to submit bug reports to Maplesoft, so I'll post this here:

Greetings, Maple saves backup files in my user directory with names like "untitled0_MAS.bak". When I leave the program on for long periods of time they get to be a nuisance. It would be nice if they were saved to a more discreet directory. I am using Mac OS 10.4.10 and Maple 11. Thank you for your time and keep up the good work. Cheers, Ed

I've submitted to Maplesoft some suggestions for Help pages in Maple 11.01. A copy is online, and comments on it would be welcomed: View 4119_HelpSuggestions--1101.mw on MapleNet or Download 4119_HelpSuggestions--1101.mw
View file details Note that the document is “live”—i.e. if the cursor is on an italicized word (preceded by “?”), and you press Enter, then the Help page comes up.
