Maple 11.00, Standard GUI, worksheet mode.

plot(sin(x),x=-10..10,legend="__never_display_this_legend_entry");

It's magic. The LEGEND() call is present in the PLOT structure, but it doesn't get displayed.

A little under two years ago, I started working on a little project we have here at NCSU. I should perhaps devote another blog entry to discussing that lovely little project... Anyway, there's a lot of Maple code in this project (as it is based in Maple), and I've had to untangle and understand what multiple programmers have done over the years. Last year, I came across one piece of code that I thought was exploiting a bug in Maple: We would take a long string of commands and parse the entire string with a single parse() command. I could never get a Maple worksheet to reproduce those results obtained from piping the command into Maple from the command line. Weird, no?

Hello, I am a brand new Maple user. I'm strictly an amateur hobbyist (at mathematics and mathematical software) in every sense, so I hope other members will understand why my questions will be so basic. I look forward to learning Maple, and will be very grateful for any assistance in the future from the Maple users community.

Could some one help me to plot this population balance equation ? see the attached file Download 4968_PBE.doc

Never Say Never The constant crying The late nights It’s all her fault We have to fight So many problems Getting lonely now Never able to see you Have to find a way somehow You’ve never fallen so quickly Like me more than a friend I’m sick of this pain It won’t work in the end Maybe one day we’ll meet in heaven Then we can be together forever No interruptions, no problems Never say never

The title says it all - although in the documentation of the Maple Toolbox for Matlab you can read that it is fully compatible with Matlab's Symbolic Math Toolbox, this is actually not the case. So better do not expect that after you install the Maple Toolbox you'll be able to use your old m-files that worked OK with Symbolic Math Toolbox - they might work, if they rely only on the most basic features. However, as soon as you need anything a little bit more complicated, you'll experience a lot of difficulties. One example for all - with Symbolic Math Toolbox you can have: >> var_str = '[a; b]' % symbolic matrix represented as char

Maple uses the GnuMP (a.k.a. GMP, or gmp) library in computing with large integers, see ?gmp .

Visiting the GMP web page one can find this interesting benchmark table. It indicates a higher known benchmark for Opteron/Athlon64 than for Core2. (I don't know that GMP makes special use of multiple cores at this time.)

It had been quite a while since I had read Joel Spolsky's great blog on software, so I headed on over and read his rather thoughtful post on customer service. I learned something from reading it, so I thought I would share it with others.

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.

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

Well hello. My name is Phoenix:) I have recently started going to school for computers, information systems, and found out you need to be good at math to work with computers. Now don't laugh....but math didn't cross my mind when I signed on, and I am horrible with math :( I am 24 years old and am still learning my multiplication tables. That was one subject I just never could find any help with as a child, and now as an adult I am afraid I am clueless when it comes to anything mathmatical. I am taking the course online, so I do not really have anyone next to me in class to help if I get confused.

Just came across and interesting blog post on language design, focusing on the architecture versus features dimension. Trying to place Maple on this, it pretty much has to co-exist with Perl in the Pragmatic column. For comparisons' sake, one would have to place Mathematica in the Consistent column. The arrow of time graph is quite interesting. Maple is firmly a 'mature platform'. Whether it is 'bloated' is a very subjective call at this point; people of a more minimalist bent would certainly say so, but compared to something like Perl or C++, it most definitely is not. However, it is rather inevitable that it will become bloated: Maplesoft needs to push out new versions for people to upgrade to, and to be able to sell those, 'new' features have to be there to warrant an upgrade, right?

Is our world could be exist in the complex space? We already know that our living space are in 3-D. But if the space we live is actually in the complex one, then that means we are living in the 6-D sapce. Maybe it is hard to say what the dimension of our space really are. One thing for sure is there always some mysteries waitting to be answered. Quantum mechanics is one big mystery in the physics, I think. What is the matter wave? What make the tunneling effect? Why we have to use the probability to describe the quantum world? There must be something we do not know yet. Is there any possibility to say that we can deal the quantum problem within the complex space, not in the Hibert space? Or is there any possibility to have a better describtion to the quantum world? Yes, I think it is.

I just found this. It's not quite Math or Maple related, but I'm sure most of you will appreciate it.
