The command "latex(expression)" attempts to generate LaTeX commands that will recreate the expression in LaTeX. For example; latex(%) will try to generate LaTeX commands to recreate the last output from Maple. Let's say I had just entered the Maple command to display an integral; for example: Int(Int(Int(rho^2*sin(phi),rho=sec(phi)..5*sec(phi)),phi=Pi/6..Pi/3),theta=0..2*Pi); If I would like to put that same integral in a LaTeX document; I could enter the following command: latex(%); Which, in Maple 9, returned: \int _{0}^{2\,\pi }\!\int _{1/6\,\pi }^{1/3\,\pi }\!\int _{\sec

There's an interesting set of posts on comp.soft-sys.math.maple about post-processing .eps plot output from Maple. Here's a link via Google Groups. The author's ideas revolve mostly about processing tickmarks and subtickmarks and replacing them with symbols. The claim is made that it's harder (or impossible) to do some things in Maple for .eps output that are possible in Mathematica or Matlab. I haven't yet tried or looked hard at the posted code, or verified the claim.

It seems to me that I found a tip (I am a beginning user) In running these three commands in Maple 10, one gets: > sum(1/(n^4+1), n = -infinity .. infinity) sum(1/(n^4+1), n = -infinity .. infinity) > sum(1/(n^4+1), n = 0 .. infinity) 1/4*(Sum(_alpha*Psi(-_alpha), _alpha = RootOf(_Z^4+1))) > sum(1/(n^4+1), n = -infinity .. infinity) 0 The last answer is obviously wrong. In other similar experiments, Maple gives the answer -infinity to the last expression, which is also wrong. Could somebody comment on this phenomenon? Many thanks in advance.

Hello, I have a question concerning PDEs with initial / boundary conditions. Now, I am trying to solve this PDE. The general solution to my PDE is achieved by: governing equation : the homogeneous diffusion equation is > PDE := diff(c(x,t),t)=diff(c(x,t),x,x); the boundary condition are > BC1 := c(0,t)=0; > BC2 := c(0,L)=1; the initial condition is > IC := c(x,t)=1; I want to solve above equation by using maple software(Currently I am using Maple 10). In this case I want to find the final expression. If you have any idea to lead this problem using this software, please help me help.

Usually exporting from classic interface as HTML works quite well (ok, not all the finer things, but with good (!) graphics and it is painless). Now I want to hide input (for readers not used to Maple that might be better), but with M11.02 the input is exported anyway. Any workaround (except using an editor for the HTML result) ?

Inspired by my own post The art of linking, I here bring an expanded version (I hope that it does not appear too self-centred to do so): You can link to other parts of MaplePrimes, or to external webpages, using the HTML tag a with its associated attribute href. This tag and its attribute you may enter by pressing the link-image  (please disregard the black background), which is located above the area where you enter your text, the result being <a href="http://"> The part between the two "'s is where the address of your link, the socalled URL (Uniform Resource Locator) must be inserted. Below, four typical link situations are treated:

• Linking to a thread: Taking as an example the thread in which the above post appears, you could write (for long URL's, as this one, use copy-paste to avoid typos) <a href="http://www.mapleprimes.com/forum/why-does-evalb-evalf-10-0-evalf-10-0-float-1-0-30-false">The other thread</a> which would appear on the screen as The other thread.
• Linking to a specific post: Each post in MaplePrimes has its own unique ID. It can be found by placing the mouse over the link email this comment of the post to which you want to link, and then reading of a five-digit number at the end of the line at the lower left of your screen (in Microsoft Internet Explorer). A link to that post is then created by appending to the URL of the thread itself the following code: #comment-....., where for ..... the five-digit ID has to be inserted. It was William Spaetzel who originally told me this. Taking as an example the above post, which has the unique ID 11566, you could write <a href="http://www.mapleprimes.com/forum/why-does-evalb-evalf-10-0-evalf-10-0-float-1-0-30-false#comment-11566">The other post</a> which would appear on the screen as The other post.
• Linking to or showing a picture: First of all you have to upload your picture using my files under Navigation. Having done so you can copy-paste the text in the column Download Link Code. This text contains both the HTML a and image tags. You can then choose to keep the full text, thereby having a clickable image (a link to the image), or you can manually strip away all a tags (remember the ends also) thereby having a non-clickable picture, as I have above.
• Linking to an external web page: Taking Maplesoft as an example, you could write <a href="http://www.maplesoft.com/">Maplesoft</a> which would appear on the screen as Maplesoft. The part target='_new' has been automatically inserted by the MaplePrimes system (click on Input format, which is located below the input text area, to see the various input formats), and so it need/should not be entered manually.

Inspired by the post Re: the physics package I decided to have a closer look at the function FeynmanDiagrams. As the Lagrangian I thought I might as well take the QED Lagrangian for a massless spinor field Q[i](X) coupled to an external electromagnetic field A[mu](X):

restart:
with(Physics):
Setup(advanced):
L_QED :=
   +Dagger(Q[i](X)) * Dgamma[4] * Dgamma[mu][i,j] * I * diff(Q[j](X),X[mu])
   +Dagger(Q[i](X)) * Dgamma[4] * Dgamma[mu][i,j] * e * A[mu](X) * (Q[j](X));

So what is the best way to put a "link" from one place in a maple document to another. So that someone can jump quickly when clicked? Thanks!

Maple 11 has been working flawlessly for me under Mac OS X Leopard, with both updated. However, while the screen output appears to be fine, the Times New Roman (and other?) fonts seem to disappear and are replaced by a sans serif font (like Helvetica or Geneva). This occurs whether I send the output to a postscript laser printer (HP 2200) or to a non-postscript inkjet (HP 5550). I vaguely remember having a similar problem years ago, i.e., prior to Mac OS X. Has anyone else encountered this problem? Has anyone who encountered this identified a solution? So far, I'm stuck exporting my resu

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)

I am trying to figure out what the heck im doing wrong when embedding the if into the loop:

for a from 1 while a<13 do
if(a=1)
then functions[a]:=m||a;
else functions[a]:=(m||a||rref[1,5]*x^(3))+(m||a||rref[2,5]*x^(2))+(m||a||rref[3,5]*x)+(m||a||rref(4,5)); end if
end do;

I get the Error, unterminated loop

Thanks in advance!

My previous blog entry was a real success. Even though my original idea about multi-part MIME has not gotten anywhere, I do now have a concise way to package a maplet with supplemental files in a single package that can be downloaded via the WWW and automatically extracted and executed. Most of the ideas were presented by acer. acer first suggested that I look at the interactive interface to the InstallerBuilder. The idea here was to embed the maplet in a worksheet saved in a help database (hdb). This did work, but was not suitable for actual use due to the overhead of the installer. In the attempt to reduce this overhead, acer then supplied some code that used march and LibraryTools. To test the product of this interaction, download the file at the URL http://www.math.sc.edu/~meade/TEST/SimpleTest.mla.

Note added: As correctly pointed out by Joe Riel in his post below, my function fromTree fails doing what it is supposed to do for expressions which contain lists and/or sets. For a version of fromTree which behaves properly (I believe) also for expressions containing lists and/or sets, see my post below. Consider the following two functions:

toTree   := x -> `if`(op(x) = x,x,[op(0,x),map(toTree,[op(x)])[]]):

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.

Hello! So glad to become a part of this community, I am loving Maple. So here is my question: I know c++ fairly well (need to freshen up) and the same idea with Java, Ive seen I can incorporate languages into Maple, or so it seems. What type of things am I capable of doing? And along those lines, any suggestions to what path to take in order to learn such powerful tools? I am currently working on a bachelor/masters in engineering and would love to know Maple better then I do my own Fiance (just dont tell her). Thanks in advance!
