  • I installed Maple 11 on an AMD64 (X86_64), Debian Linux machine. The installer seems to work fine, but maple does not work: psz@potenza:~$ /usr/sms/share/maple/11/bin/maple Maple initialization error, invalid license return code psz@potenza:~$ or maybe psz@potenza:~$ /tmp/11x/bin/maple Maple initialization error, Signal received during initialization: UNKNOWN (13) psz@potenza:~$ I suspect that this error is caused by the installer creating some 32-bit binaries (that cannot work on a 64-bit machine): psz@potenza$ file bin.X86_64_LINUX/* | grep 386 bin.X86_64_LINUX/libjogl.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped
    how do we solve elliptic PDEs with boundary value problems in maple 10
    I have a new 64 bit machine with 8GB or ram and a CORE-duo processor. I just installed Maple 11 on this machine and it can't seem to access all of my memory. Programs which ran just fine under Maple 10 crash the kernel under Maple 11. The same problem works just fine on my home machine which is a 32 bit machine with 2GB of ram. What's up with Maple running on an 64 bit machine?
    hi, i made a markov model with 2 treshold values (k and n, n>k) and 3 maintenance activities. i write my availability equation: for a = λd / (λd + λin) P(0,0)= 1 / ( k + ((k-1) * (λin/μin)) + ((k-1) * (λin/μm)) + (a * ((1-a^(n-k))/(1-a))) + (a * ((1-a^(n-k))/(1-a)) * (λin/μin)) + (a * ((1-a^(n-k))/(1-a)) * (λin/μM)) + ((a^(n-k) * (λd/μD)) ) Availability = P(0,0)*(k + (a * (1-a^(n-k)))) i want to find the optimal λin which max. the availability.. is there any way to solve without giving any numerical values??
    Another pesky student question. Is the speed of light an asymptotic, or limiting value that no other body can perfectly attain ? Does light travel at exactly this value or very very close to it? Would it make sense to try to exactly attain the value of c with something other than EM energy, or would our attempts be similar to taking a limit like in simple calculus ? v/r,
    For those interested in financial Math: A classical in mathematical finance is evaluating option prices by binomial trees. This has many advantages (like easy, but coarse results for American options), but it is well known to quite inaccurate for various reasons - even for European options. The 'best' known improvement is due to Leisen-Reimer. They all suffer from low order convergence towards a continuous model. The standard reference model is CCR, the Cox-Ross-Rubinstein tree.
    Hi everyone! recently i tried to install maple 10 to my new laptop (runs with windows xp with 2gb ram). The installation went well, just that maple 10 didnt execute at all. It seems that only maplew.exe runs, but not maple.exe (I looked in windows task-manager). Anyone has any ideas?help me please....
    I have just read a wonderful paper Magic Ink: Information Software and the Graphical Interface. The most memorable section subtitle being interactivity considered harmlful. This is a real treasure trove of wonderful design ideas for interfaces for information-rich applications.

    I have a question regarding privacy with respect to uploaded files on mapleprimes. It has to deal with where public worksheets are downloaded from. I upload all of my worksheets as public files to ensure the quickest and greatest amount of help to my requests. However, my question is when those public worksheets are downloaded are they actually downloaded from the actual creator's machine (e.g. C: mydocuments...etc), or from somewhere else ? hope that question came across clear. v/r,
    To put it simply - it's about the grandkids. As anyone who is a grandparent may understand, once you have grandkids you spend time reflecting back on your own life and no matter where you've been, or what you've done, you always want them to have the opportunity to do better. Having left school at 15 years of age    ( for somewhat noble reasons )   I never learned or had the opportunity to learn the math that I later always wished I had. My life has been so busy raising my family and working the kinds of jobs that many who use Maple will never have to work, that I never had the opportunity to spend the time to further my education.
    In Maple 10 today I exported a graph to eps, with the intention of using the LaTeX package psfrag to jazz up the text. I used textplot to place the tags into the eps file as I have done many times in the past--using Maple 9.5, 8, etc. To my horror, in Maple10, the textplot gets placed into the eps file in some hopelessly cryptic way, and psfrag fails to find the tags, and LaTeX replacement of the tags fails. I generated the eps file by right-clicking on the graph, and so I decided to see what happens the other way...click on the graph, select "plot" on the menu, then "export" etc. This worked, almost. I got a simpler type of an eps file, and with this file, LaTeX was able to replace the tags I put in the eps file using textplot. Almost: when I applied the functor dvi2ps, color was lost!
    Using Maple 10 on windows XP machine (laptop and desktop). During certain operations/calculations, the screen will flash. This also occurs when opening a maple document that needs to recalculate - the screen flashes repeatedly during the re-calculation. Has anyone else seen this? Regards, Frank

    Here is another great comic from XKCD, I hope you like it:

    To listen to my own advice, here is a use case: I use 'recent posts' navigation a lot (thanks). Sometimes I read a post to which I want to reply, but I don't have the time to do that right now, but when I do have the time, I have forgotten which post that was. Actually, I can think of 3-4 such posts right now... So I would like to be able to 'mark' a post, so that I can come back to it later. Sure, I could use my browser's bookmarks to do that, but they are already a mess as it is. I think it would make more sense to keep mapleprimes-specific things in/on mapleprimes.
