I recently purchased a Maple e-book, and I noticed a few lovely features of which I would like to take advantage. The first is the ability to create a compressed worksheet. There seems to be a painfully simple mechanism behind compressing and uncompressing the worksheet, since when the worksheet is opened with a text editor, the first characters are (if I recall correctly) "<compressedworksheet". I cannot find any documentation inside of Maple detailing the compression and uncompression of files. Thus, I ask you, Maplesoft: How can I compress my worksheet files in this manner? The second feature of which I would like to take advantage is the use of a license file. Looking at the XML code of the compressed worksheet, it seems that one only needs to make reference to the location of a license file in order for Maple to look for the license file. The license file itself is very short--only about 4 lines--which makes me assume that the license file checking mechanism is similarly simple. Again, Maplesoft: How can I make and use my own .dat "license" files?
I am trying to plot the equations shown in Figures 5 and 6, which are solutions to Equations (14), (15), and (16). These equations are developed in the Lo paper (attached). I am working through the symbolic solution by hand and would greatly appreciate any suggestions on how to set these equations and the graphs of the same in a worksheet. Thank you for the assistance anyone may offer. Wayne Bell Download 4865_Lo_p691.pdf

What is the fastest code for integer dot product in Maple ? I am currently using the inner command, however there seems to be a lot of overhead. It is easily slaughtered by GMP. I was wondering if there is a dedicated external routine or something else that I can call ? I want to avoid linking in a C library just for this. On a related note, I think Maplesoft should develop a companion to the LinearAlgebra:-Modular package that supports fast operations with dense integer matrices in compiled code. I know the LinBox library supports this, maybe it could be linked in ? I actually don't
I am having a lot of trouble converting my LaTeX files to .qu with a wide variety of problems. The first one is a successful conversion but instead of an [OK] I get the message "Error Handling". LaTeX3.qu: Error handling In being fed up with the converter, I added questions and converted them one at a time. The problem is with this particular question, text below: Download 5024_LaTeX3.tex

How do I parse the response string with Maple TA? I can make my code work just fine in Maple but that is assuming what type of string $response is. If someone has dealt with this before, I would appreciate some ideas. I am asking for three parametric equations and need to seperate them and use all three for determining validity of the answer.
Sooner or later, you'll like see the following "tip" in with the tips that load when you start Maple, but in case you've overlooked it you should really give this one a try. Just type in: ?examples/index
This may have already been resolved but in case some people are still having problems... If your maple calculator is not working (ie not giving you an answer .. just giving you a blank line) your firewall may be blocking the java.exe script in your maple\jre\bin directory. Just allow access for this file. So just create a new rule in your firewall to allow full access for the maple\jre\bin\java.exe file and voila your calculator should now be giving you some answers. Hope this helps. And sorry for posting again if someone already mentioned this in the past.
Anybody can explain me how to author a question in Maple TA environment using Flash Images. Thanks Ivan
Hi. I'm having a problem getting questions involving ln()and abs() operators to evaluate correctly. For example, when creating maple graded questions, I set the correct answer to say ln( abs( x^3 + 12 ) ). So when the student enters this answer in text mode, everything is fine. In symbolic mode if ln( |x^3 + 12| ) is entered everything is fine, however, if ln|x^3 + 12| is entered, maple TA says wrong. The lack of parenthesis gives a wrong answer. Does anyone know how to make maple TA more tolerable in this situation to evaluate ln|x^3 + 12| as a correct answer? Thanks
Is there a keyboard-only way to enter equation labels that will not 'zap' the focus away to a dialog box just to enter a label? While the 'look' of the equation labels is kind of nice, I find entering them extremely annoying (zapping focus is really awful UI design).
I observe that within graphics numbers are displayed according to local settings (so 0,001 stands for 1/1000) - no problem for me, but annoying, actual output displays with a point as decimal separator. For pretty display I sometimes use something as 'eval(expr, x=1)': '%'=% which works fine in mws, but in mw it displays the eval statement - is there a workaround for both kinds of sheets? And saving a mws as mw does not respect the font size for 2D output (it changes mine from 10 to 12 (and behaves odd, it always uses italics, but we had that already i think). (Win XP home SP2,
i WANT TO DEVELOP A MICROCONTROLLER BASED PID TEMPERATURE CONTROLLER.THE USER WILL SET THE DESIRED TEMPERATURE THROUGH KEYBOARD.I WILL BE USING A TEMPERATURE SENSOR(IC LM35DZ) WHICH WILL BE INPUT TO MICROCONTROLLER 8051 WHICH WILL IMPLEMENT PID ALGORITHM TO CONTROL A RELAY AND HENCE EITHER TURN ON A HEATER OR A COOLER.AN LCD WILL ALSO BE INTERFACED TO DIPLAY THE SET TEMPERATURE AND ACTUAL TEMPERATURE. I DO NOT KNOW THE C CODE FOR THIS.IF ANYONE HAS WORKED ON SUCH KIND OF SYSTEM ,THEN PLEASE SEND ME THE CODE.I WILL BE REALLY VERY GREATFUL.
I have a large set and I would like to do the following efficiently: 1) use selectremove to split off a part of the set, based on a function f 2) map a function g onto the selected set 3) (optional) map a function h onto the removed set I don't actually need 3) however I think it would be useful. My problem is that the function g is easily computed while computing f, so something like the following is 2x too slow:
S, R := selectremove(f, big_set);
S := map(g, S);
On the other hand, g outputs a result of a different type, so I can code g to return the identity unless the condition in f is satisfied:
I am using maple 11. I have an HP printer which I verified is working corrrectly. I have a document made in document mode that I stored in a file, and when I print it sometimes it comes out ok and sometimes it comes out with everything about double size and I don't know what I am doing to cause the double size. When this happens I go to file, print preview and click on double page, and then single page at the top and everything seems to print ok in normal size again. But now I just completed another document and tried to print it out and it printed again with about double size letters but when I go to file print preview, double page and single page are not enabled and I don't know why and consequently I have no way to print out this document.
I am using OpenMaple (kv->rtableCreate or RTableCreate) to allocate large rtables which I then fill with data before returning to Maple. It seems to be slow. For example, a table with 120 Mwords takes 1 second to allocate and 0.640 seconds to fill. I suspect this is because the table is initialized to zero. I would like to skip this initialization and maybe use malloc to allocate the table, however I want it to behave like a normal Maple object (ie: garbage collected if not referenced, etc). The documentation says it is important to set rts->foreign to true, but it doesn't say why. Will this prevent garbage collection ? I would also like to know the purpose of rts->foreign.
