  • Well, I was quite pleaseantly suprised by how much some people at the Maple Conference 05 knew about Maplets:-Tools Set and Get. Unfortunately, DocumentTools GetProperty and SetProperty were designed to be completely different for no appearent reason. Well, a reason was given, but I didn't buy it... Anyway, here is DougsDocumentTools, which works just like Maplets:-Tools Set and Get:

    Early this season, after the Maplesoft team came out on the wrong side of a 13-6 loss, we were frustrated by the team's inability to score more runs. The previous year we averaged 14 runs a game. This started me wondering, just how many runs can our team expect with a given lineup? Suppose you assume that it takes three hits in an inning to start scoring runs. Now, let's assume you have five .500 hitters coming up to bat. What is the probability that you'll get 3 hits among those five batters, thus scoring one run?

    Here are two illustrations for how one might want to check to see if g is the same as f. The attached file is a Maple 10 worksheet.

    You may have noticed that we've introduced prizes to get people more involved ... bribery is not beyond this crew to make this site successful.
    Respond to questions in the "How Do I? (Newbie)" or the "How Do I" forums and you will be eligible to win this great shirt.
    Joe Riel and Thomas Richard posted in their blogs solutions to the latest IBM Ponder This challenge and some related questions. From the name of the attached files, one can deduct that Thomas Richard is user No. 50 and Joe Riel is user No. 84. Being curious about my user number, I also decided to attach a worksheet.
    Forum pages do not seem to have a printer-friendly version option as the Maple FAQ section pages. Is it possible to add it? Alejandro

    Chi^2 calculations above some "size" or "complexity", using Maple 9.5 and Global Optimization Toolbox (GOT), may produce after some time of calculation error messages like:

    "Execution stopped: stack limit reached.
    The kernel has been shut down. Further computation cannot be performed."

    Seeking workarounds, I have looked for information at ?kernelopts for kernelopts(stacklimit), but it was not very useful:

    "Limits may be raised or lowered. Maple limits may not be raised above any system defined hard limits. "

    A question was asked in the forums about series tests. I saw that this would also make an excellent weblog entry as well. In answer to the questions: How can I get Maple to determine if a series converges or diverges? and How can I obtain the general representation of a formal power series for a function? I offer the following advice:

    RSS feeds allow people to easily keep track of updates to their favorite websites. Say that you have 50 websites that you check every day for updates. What if instead of going to each of those individual websites, you can simply load your RSS reader and see which websites have been updated at a glance.

    To use RSS feeds you will need an RSS reader. Here are two pages that list many different readers: http://blogspace.com/rss/readers and http://allrss.com/rssreaders.html. My favorite reader is Bloglines which is a web based reader that allows me to view my RSS feeds at any computer with a web connection.

    Because all versions of Maple for linux share a common user initialization file, ~/.mapleinit, this file must provide a means to branch if specific customization is desired for different versions of Maple. I've come up with a flexible, if slightly complicated, scheme for handling this.
    What is the point of the everthing but forum? It seems like the topics that might go in that forum could be just as easily (and perhaps more appropreately) posted as blog entries. Do people really want to discuss their hobbies in the Maple Primes forum? I think it is better not to have off topic forums like this because it might confuse less savy (or ESL) users.
    I've released an addon package for the PolynomialIdeals package in Maple 10. It collects the routines which never made it into Maple 10 as top level commands, and a few new routines are thrown in there for good measure. The demo worksheet lists all of the commands. You can view it online and download everything at the Maple Application Center (link).
    This is more a question than a suggestion... under the "new content" tab, what does the "red star" beside some of the topics listed mean? At first I thought it indicates new topics added since I last logged in. But it doesn't seem to be consistent since I remember reading some of topics with "red star" before... Also, is there a way to list only those topics/threads with new materials (replies)? Currently, the new content tab seems to be listing ALL topics/materials in reverse posting order. But some threads/topics added later might not have new replies while some older topics would have new responses... this makes it hard to quickly locate what is new... (I know RSS would probably work in this case... but I kind of like to have a page of listing and quickly browse through it...)
