  • FYI: Maplesoft just released DynaflexPro , a new product that generates equations of motion for physical systems (including mechanical, mechatronic, and others). Automatic generation of model equations is one of the most powerful and popular applications of Maple in the engineering fields and Dynaflex offers a lot of tools to make this more efficient.
    A colleague has been frustrated by the apparent limitations to Maple's abilities to "solve" inequalities. This does appear to be something that should - and could - be improved with a little effort. The typical problem under consideration is the epsilon-delta definition of limit. Ideally, it would be nice to execute a command such as
    > solve( abs( f-L ) < epsilon, x );
    
    and receive an answer in terms of intervals.
    I have a classic-worksheet version of Maple 9.5 that runs as an X11 application on my Macintosh. Is there a classic-worksheet version of Maple 10 that does the same? If so, where can I get it?
    It would be good if I could tell looking at the list of messages in the Inbox or other folder, to which of them I replied. Also, it would be a nice feature if I could see in the Sent folder whether my message to somebody had been read, or not.
    Hi all. If you have a question on how to do something on Maple, can you post them in a Forum? Either "How Do I? (Newbie)" for new users or "How Do I" for experienced users. We'd like to reserve Blogs for short articles and thoughts. Some recent blog postings will be moved by the moderators to appropriate forums. Thanks! T4.
    It would be helpful to have a tool bar, menu, or list of links for selecting another forum from within a forum. The current structure requires the extra step of returning to the forum list.
    Does anyone have advice for content in a maple tutorial for calculus students and any math students for that matter? I am doing a tutorial to help students avoid the fear of Maple and try to help them to avoid common mistakes. Any suggestions would be great!
    dear all, I want to write a greek letter (tau) in the legend of a figure. how can I do that? thanks!
    dear all, how can i move legends from bottom (default) of a figure to the side? thanks!
    Hi, I have a problem printing a worksheet under OS X 10.3 (I've tried it with various minor versions of 10.3 and they all behave the same). The worksheet contains a few plots, and when I try to print, the printout stops at the first plot. The plot is not printed, nor is any of the subsequent material. The printer does generate blank pages, though (and it generates the "correct" number of blank pages). So, text up to the first graphic prints, but nothing after that point shows up. If I use Maple's "File / Print Preview" command, it displays a preview with all the worksheet displayed the way it should be.
    We have Maple 10 ryunning on a large Univerity network of Windows XP machines. Unfortunately Maple can't save changes in options such as to use "Maple input" rather than "2-D input". The reason for this (according to our tech people) is that Maple tries to write to user profiles directly rather than using the API (as it should), and so it is missing our redirection of the profiles. 1) Are other people having this problem? 2) Is the above correct? If so, why are Maple using these hacks and not implimenting things "properly". 3) Is there a fix? I'd be grateful for any info.
    The map function is a particularly useful Maple function. I use it frequently and thought I understood how it worked. However, I recently discovered an interesting feature of mapping over vectors, matrices, Vectors, and Matrices. That is, the order of application of the mapped function depends on the data type and may be indeterminate (for table based structures).
    Hello All: I am working on generating some correlated sequences using Matrix Exponential techniques. there seems to be some problem with the way maple manages memory (or am i doing something wrong?). specifically, in the code below, i am calling a few functions inside a for loop but none recursively. so as the for loop progresses my stack (memory; seen as PF Usage in win XP) size should not really blow up. right? but in Maple 9.0 and 10.0 this below program would give a "Execution stopped: stack limit reached." exception after about 30000 executions(I am running on a WinXP machine , about 2.8GHz, with 512 MB RAM, also checked on a machine with 1 GB Ram; and another 1GB in page file size). But the same program seems to work alright on the same machines with Maple8 running (i uninstalled maple-9 and installed maple-8 in one case). I could go up to 300,000 iterations without any problem. And the memory would go from about 250MB (PF Usage) to about 800MB. So even in Maple 8 there is some stuff that is being dumped on the stack; i tried to run Garbage collector (gc()) function once every 500 iterations; it did not make any difference either. Can anyone please look into it?
    Hi, Colleagues, I wonder if sombody has developed a Maple code for parameter continuation of codim 1 & 2? Evgeni
    Hi, Colleagues, I need to use two colors for positive and negative values of a plotted function and I am trying to use a piecewise switch. My atempt was something like plot(sin(x), x=0..13, color=(x->piecewise(sin(x)
