Please see below:
> deq := diff(y(x),x,x) = A*exp(y(x)/vt);
> deq2 := diff(y(x),x,x) = A2*exp(y(x));
> #y := unapply(rhs(dsolve(deq,y(x))),x);
> y2 := unapply(rhs(dsolve(deq2,y(x))),x);
If I let two dsolve go, it gives error message for the second. However, commenting one and letting one go will always works perfectly. What's the problem, any bugs inside Maple. I tried in Classic Maple and Maple 10. same problem happend.
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?
I want to write a greek letter (tau) in the legend of a figure. how can I do that?
how can i move legends from bottom (default) of a figure to the side?
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.
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 to all. My first post. I'm new to Mapleprimes, but have been involved with Maple for a few years.
I would like to have a generalized genetic algorithm optimization tool that I could use to explore various engineering system optimization problems. I'm not aware of anything "out there" in this area. Is anyone aware of such a tool (open source or commercial)?

Is there a trial version for Maple 10.0 if so from where I can download it.
The zipped code for "Pricing Arithmetic Average Asian Options" is missing sobol.h (to be used by the source ArithmeticAsian.cpp).
Could someone please add that header file?
Does Maple 9.0 work with Mac OS 10.4?
Does anyone else have trouble with Compiler:-Compile on a Mac?
I have gcc 4.0 installed on Mac OS X 10.4.2.
For example for,
p := proc( x :: float ) :: float; 2.3 * x end:
cp := Compiler:-Compile( p ):
cp( 1.1 );
I get the message:
Error, (in LinkDSO) linker exited with nonzero status 256: /usr/bin/ld: can't locate file for: -lcc_dynamic
But on my home Mac, which I think is configured in exactly the same way, the same commands work!
After a lucky google search I found a reference to the problem. A symbolic link is removed by the installation of gcc 4.0. Running Disk Utility to fix permissions repairs the link, and now Compiler:-Compile works!
I am using Maple 10. In the tools menu I click "check for updates" and then go through the procedure of updating. In the end I get the dialog box "Update was unsuccessful because of the following reasons" (1) You might not be logged in as administrator .I am logged in as administrator as a matter of fact. (2) You might not have enough disk space. I have plenty of disk space left.
I have no clue as to how to get around this situaton. Please help.
Once again Maple has screwed things up in a new version. The material in my book, Differential Geometry and its Applications, on unduloids using elliptic functions doesn't give the correct pictures in Maple 10. Maple 9.5 worked fine. Also, something has been done to the simplification routines. In Maple 9.5, the metric and second fundamental form for unduloids are simplified to a point where they can be easily identified. In Maple 10, all that you get is a huge mess. At the Maple Workshop in 2002, I asked about these issues that have cropped up before (the worst being the transition from the wonderful Maple 4 to the horrendous Maple 5).
how can I plot a vertical line? for example x=5, starting from y=0 to y=10.
