  • Hi all, Is there a Maple .INI file that I can edit so that I do not have to continually enter packages or change fonts for styles that I wish to use instead of the default values. For example: with(package) with(package) Set Maple to be initiated with any package without repetition? TIA Larry Ciak aka malt_master@comcast.net
    I have programmed a procedure to calculate certain polynomials associated to matrices. There is a variable for each column of the matrix, say z1,...,zn, and the polynomials get quite large as the matrices grow in size. The procedure gives the correct answer but, for large matrices, the terms in the resulting polynomial are not collected properly. For instance, terms z1*z2*z3*z4 and -z1*z2*z3*z4 might both appear. "Simplify %;" does not cancel these terms. By copying the answer and pasting it as a command, I can cancel the terms but most answers are so big that copying cannot be done in practice (hundreds of pages).
    I try to solve a large class of origami folds using Maple, this is the mw file (at this stage, only one step missing, I'm not very good with trigonometry using Maple).

    At this end I only have to express the angle alpha in function if the anlgle theta and the lengths y_a and y_b.

    More explainations soon.

    The question of how to scale the x-axis with intervals of Pi has been raised on a number of occasions. Inspired by a contribution from Will, I produced the procedure and examples shown in the worksheet attached below. Hopefully, Maple users will find it useful. J.

    Does anybody know why Maple's support of PDF is so poor? I posted a forum topic entitled "PDF support" in the past but didn't get any satisfactory answers. Suppose that I want to automatically generate a bunch of PDF files in Maple and manually saving each one as PDF isn't an option because it is too time consuming? Am I the only Maple user who has ever encountered this option? A search of the web seems to indicate that this is the case. I want to use Maple over Mathematica, but this is one issue that has prevented me from making the switch (permanently) so far. I am currently running Maple 10.04 for Mac on OS 10.4.8 on a G4.

    Hi all, I am Using Maple 10. i am getting a frequent bug When i plot a 3d graph. Description: In a 3d plot, if i rightclick after rotating the graph, maple exits automatically. can somebody please tell me what's the problem? Thank you Divahar.J Indian Institute of Science, Bangalore, India.
    Hi Community! I am using maple in excel and... I have a question When I introduce this expresion =Maple("array([[1,2,3],[4,5,6],[7,8,9]]);",A18:C20) The output is: matrix([[1,2,3],[4,5,6],[7,8,9]]) on cell A18. Why? The output don't share on each cell this array. On the cell A18 would be the first element of the matrix, 1 On the cell A19 would be the second element of the matrix, 2 ...until the cell C20 it element would be 9. Which could it be the solution? I hope, you understand me Thanks!
    I'm wondering about the complexity on Gröbner basis. I think I've heard something about O(2^2^n) or something like that. Is that true?
    For example,4-by-4 peridentity matrix has the form 0 0 0 1 0 0 1 0 0 1 0 0 1 0 0 0
    convert(407,binary); 101100111 I want the vector [1,0,1,1,0,0,1,1,1]. I don,t make this. Please help me!
    I teach a Maple course in a computer lab. There are many problems with Maple crashes. I've had the autosave feature disabled, which seems to help some. I'm running Maple 10.04 (New GUI version, Network, Windows XP). Last year, I used Maple 9 Classic and it worked beautifully. Has anyone had a similar experience? Any suggestions for improving the stability of the program ?
    Hi everybody! a few weeks ago I asked in this forum a question: http://www.mapleprimes.com/forum/partial-differetial-equation-heat First I have to say that is really nice how easliy it solves the problem. Now, I really need to see values in the solution (I mean, by given x and t). In addition, I want to create graphs of the temperture as a function of t (I mean to state x, and then to check the temperture as a function of t in this x). Only I know is to do graphs of the temp' as a function of x) How can I do all of those things? Thanks A LOT !!! RedFox (:
    Hello all ... while I was in Japan, Paul Goossens filled in for me as guest host of MapleCast Episode 10. Special guest is Dr. Marvin Weinstein of the Stanford Linear Accelerator Center (SLAC). Paul also interviews yours truly while I try to recover from jet lag in Philadelphia. T4.

    We have just launched a brand new version of MaplePrimes that has many new features, tweaks and a fresh new visual design. These features are focused on making the site as easy to use as possible. The site will be coming out of beta very soon and we would like to get as much feedback from users as possible. Please comment on this post with any comments that you have about the new version of the site.

    New features for the site include:

    • Maple Ranking - All users are rated based on how active they are on the site. You get points for every posting that you make to the site. The more points that a user has the higher their Maple Ranking.
    • Maplesoft.com login - You can now log into the site using the same information that you use to log into Maplesoft.com. If you already have a MaplePrimes account you can continue to log in as you did before. If you have a Maplesoft.com account with the same e-mail address as your MaplePrimes account your accounts will be linked together.
    • Redesigned file manager - All files automatically have their own page that makes it simple to paste the contents into a posting. Images are automatically resized and creating HTML versions of worksheets is easier.
    • Toolbar added to entry boxes - Buttons now appear at the top of all entry areas on MaplePrimes. This makes it easy to enter HTML or Maple code. Quick links to the file manager are also provided.
    • User profile images - Upload an image to your profile that will appear next to your name on all comments that you place on the site.
    • Email pages - A link is now shown on the bottom of every post that lets you forward the post to an e-mail address. You can use this to share a post with a friend or colleague or save it for yourself.
