Would someone try the Integration Tutor with csc^3(x). On SuSE Linux 10.3 with maple 11.01 it just loops through the Parts rule. Endlessly it seems. Worksheet works fine though. Tim

I am writing to discuss an issue which arises due to a Java bug combined with updated X11 libraries. I have been trying to get Maple 11 to run in a new version of Fedora Linux (F8). After a lot of searching I have found a solution. Note that unless the Maple developers issue a new corrected CD image changed to work with the new libX11 library then this fix will be required on all linux machines with updated libX11. In my case this came to light after upgrading my computer from Fedora 7 where the application was installed (and kept in an untouched partition during the install of F8)

Is there anybody, MapleSoft staff included, of course, that could give some help or advice on the issues raised in thread1 (which died unresolved) and thread2 (which I somewhat expect to share destiny with thread1)?

I am getting the following error when I attempt to start Maple 11: Cannot launch Java application Uncaught exception in main method: java.lang.NullPointerException I have followed all of the other threads of a similar topic and adjusted my java settings as recommended, such as: 1. Copied crimson.jar into the library/frameworks/maple.framework/versions/11/java/ 2. Modified my java preferences so that my runtime settings are set to j2se 1.4.2 and my java application runtime settings are set to j2se 1.4.2 then j2se 5.0. After making these changes I have rebooted, with no change in the error message. I have attempted to run the crimson.jar by double clicking on it and get the following error:

hello to everyone! I have a problem with the maple toolbox for matlab: i can't use the command setmaple to move my equations from matlab to maple. An example: i create two symbolic variables in matlab >>syms x y; then i set: >>cos(x+y) ans = cos(x+y) and now i try to move the equation to maple: >>setmaple ('h',ans) ??? Undefined function or method 'setmaple' for input arguments of type 'sym'. i'm using maple 11.01 and matlab 7.4.0. I tried updating toolbox for matlab but it didn't work. Some suggestions? Thanks...

Since upgrading my OS to OSX 10.5, printing Maple output does not work, at least not well (See attached PDF at Download 513_Maple_Print_Problem.pdf
View file details). Why is this happening? I have tried printing worksheets on three printers from two different manufacturers with the same results. (I am using a MacBook Pro 2.33GHz, 2GB ram, MAC OSX 10.5) Any help would be appreciated, as I cannot use Maple to generate materials for my classes at this point. Lance N.

Here it is. If you are running windows vista on your machine and installed maple 11, you will shortly notice that you cannot save documents which is a little annoying. After a lot of reading and understanding how maple works as a sofware, I figured out that maple installs its own version of Java Runtime Envenrinement commonly known as JRE. The hick is it is not compatible with windows vista. Here is the solution I propose for you: 1. Go on Java sun`s website and download the latest JRE version. You will need to install it... https://sdlc5e.sun.com/ECom/EComActionServlet;jsessionid=A61F1EC27C11159DC1B22D3FBC2E7AB0 this is the website of the latest version I know of.

Can evalc be persuaded to return for

assume(x::complex):
+1/2*evalc(x + conjugate(x));
-I/2*evalc(x - conjugate(x));

the real and imaginary parts of x, respectively, i.e., Re(x) and Im(x). Further, can evalc be persuaded to let

assume(u::complex,v::complex):
evalc(Re(u)+Re(v)-Re(u+v));
evalc(Im(u)+Im(v)-Im(u+v));

return zeros identically? It does return zeros identically if either u or v (or both) is real-valued. But not if u and v are both assumed complex-valued. Why not?

Below is a link to a file I uploaded showing an example of using assigning the value obtained from eval() to a variable and then using evalf() versus using eval() inside of evalf(). The fact that there is some difference is not surprising; it's the sheer amount of difference that amazes me--up to 100%! Do also note that the difference "settle down" over time, which is to be expected. View 413_odd_rounding_example.mw on MapleNet or

Hi. Issue: Anytime I open a recently saved Mpl worksheet, all of my 2D-MATH has been erased and replaced with a simple question mark (?).. And I've tried to open it on a Linux-based OS and trying executing it for like a hundred time. Nothing seemes to work.. Solution needed. Thanks for your time and help. Vic

Is it possible to have installed both Maple 9.5 and Maple 11 without interference? The reason I ask instead of just trying it out myself is that when I tried to uninstall Maple 11 some days ago (in connection with my roll-back to Maple 9.5) it got stuck. So instead of risking that again, probably with some unfortunate consequences for the integrity of the registration database, I thought I might just ask your guys first. Some of you might wonder why I want to have both installed. But I thought that I might continue using Maple 9.5 for my usual research, and then using Maple 11, possibly in conjunction with a text editor, for things which cannot be done using Maple 9.5.

So I am trying to install Maple on OSX 10.5 and I am getting this error: Cannot launch Java application Uncaught exception in main method: java.lang.NumberFormatException: For input string: "TipCount" Any suggestions? I have a feeling it is not a problem with 10.5 but just a Java problem in general. Any help would be greatly appreciated! Thanks! Brandon

I have been trying to replicate the results of an analysis which uses elliptic integrals of the first and second kind (see an earlier post titled "Solve This! - Elliptic Integrals" for a copy of the analysis and a Maple worksheet that plots an equation containing an ellipitc integral). Dr. Israel provided the Maple commands that generate the plot; however, the results are not in agreement with the paper - not even close! In an attempt to validate the EllipticF(z,k) command in Maple, I have generated a spreadsheet (attached) which uses an EllipticAddin to generate a table of values for a range of phi from 1 to 45 degrees and theta over the same range. As you can see from the workbook, the Addin has successfully generated a table that is in perfect agreement to five decimal places with the results given on page 94 of "Elliptic Integrals", 1st Edition, by Harris Hancock, Wiley & Sons, 1917 (available in PDF format from Google). The sheet that uses the EllipticF(z,k) command is not in good agreement with the table from Hancock's publication.

Consider, just a test example, the following list of lists of positive integers ordered ascendingly

L := [[1,2,7,12],[3,4,5,6],[1,2,5,9]];

I would like this list of lists ordered so that [1,2,5,9] precedes [1,2,7,12], because 5 < 7 (the first two elements being equal), and [1,2,7,12] precedes [3,4,5,6], because 1 < 3. I think you see the general scheme. That can be achieved with the following code:

with(ListTools):
swapLists := proc(L1::'list'(posint),L2::'list'(posint))
   local L;
   L := MakeUnique(L1-L2);
   if L = [0] then
      false
   elif L[1] <> 0 then

In connection with setting attributes on Arrays, as discussed here, I have run into a problem which boils down to the following: why does the code (which is only for test purposes)

p1 := proc(x,y)
   table(['x' = x,'y' = y])
end proc:
p2 := proc()
   local x,y;
   x,y := 1,2;
   table(['x' = x,'y' = y])
end proc:
p1(1,2);
p2();

produce two different outputs; the former, p1, evaluates 'x' and 'y', even though they are surrounded by unevaluation quotes, while the latter, p2, does not?
