Hi, I am having trouble with the list L:=["2", "abcde"]. I want to get L[1]/4=.5. But L[1] is not a number. How can I convert that? Thanks.

Because my ISP no longer offers home pages, I'm putting the source to maplev-mode here.

maplev-mode is an Emacs major mode for developing Maple code. Its features include:

• font-lock (highlighting) of Maple keywords
• automatic indentation
• syntax checking (via Mint)
• online Maple help
• online display of Maple procedures
• imenu support
• auto-fill support

It works properly with NTEmacs on a Windows machine and with GNU Emacs on a Linux box. It has been tested with GNU Emacs 21.2. It is supposed to work with Xemacs but the testing done with Xemacs has been minimal. The manual is badly out of date.

The current version supports Maple 11 and previous releases of Maple.

I use a dark background, but the maplev-mode can be configured to use a light background. Clicking on the highlighted "on line 13" message in the mint buffer moves the point to that location in the source buffer. Download 84_maplev.zip

Ref: Kahan (Jan 2007): How Futile are Mindless Assessments of Roundoff in Floating-Point Computation ?

I wanted to know, how Maple behaves on the example given in \2475 of that working paper (where other

systems are considered, mostly Matlab) and thought it might be of interest here in the forum.

I have a string in the form ss:="abcd # efg # hijk, lm_r, stuv_k": Is it possible now to write it as [ [abcd], [efg], [hijk, lm_r, stuv_k] ]: Thanx, Kharal

Hello, I have a question about Mathematical Expression Component in document. I tried to use it in my maple document and of course I looked at the help about it. There is a discription about another component, I think. The reason of it is that the dialog of component property is different in a help and in a document. I do not know why. I try to use it in Maple 10.06. The following figures show the situation. Of course, problem of this component is not only in different property dialog but also in functionality. Figure from help Figure from document Problem with this component is described also in the document here. Thank you. Vladimir

Scientific Computing recently posted their thoughts on the usefulness of scientific calculators. They also had an interview with a representative of Texas Instruments. When the rep was asked the question of "why would I still use a calculator now that computers are so cheap?"

The final explanation, and the only one that Scientific Computing was satisfied with was that for a calculator, "you can take it into an exam, but most exam systems do not allow you to bring a computer in."

For myself, I haven't touched a calculator in quite a while. For simple problems, I will just use Windows Calculator, or Google. And of course, for anything else, I use Maple.

If you want JordanForm to give the matrix Q that Jordanises the Matrix A then the Help pages tell you to use JordanForm(A, output='Q'); Unfortunately this doesn't work inside a procedure that has Q as a local variable: proc(A) local C; JordanForm(A, output='C'); end proc: generates an error on execution. I'm not sure whether this is a bug although it is surely a poor state of affairs. I don't understand why the syntax has been set so that the value of the option is the global name C - is there some possible advantage to it? . Surely it would avoid all such problems if all options and option values (of this sort) were either reserved words or strings. So then the syntax would be

hi there, The "Maple Advanced programing guide" was produced using a special version of Maple that reads and updates latex files, where can I get such a version? ANYONE KNOWS?

Could anyone help me? How to get the set of non-neg-int solution of x+y+z=n?

Hi! I was trying to execute a simple ComboBox maplet in Maple 11, but everytime that I try to make use of, the below message is presented: Execution Stopped: Stack limit reached. Can anyone help me? Thanks, João Paulo Laudares

Hi I am seeking to the analytic solution of the integral int(((alpha^2+mu^6/alpha^4)*E[1]+(alpha+mu^4/alpha^3)*E[2]+(1+mu^2/alpha^2)*E[3]+1/alpha*E[4])*omega/sinh(Pi*omega)*(alpha-a-I*k)^2*exp(-2*I*omega*theta),alpha=-infinity..infinity) where omega:=1/2*(alpha-mu^2/alpha) and other parameters are real constants. Any helping would be appreciated. cheers Sayed
