## Matrix operations over finite fields?...

If the finite field is Zp (p a prime) then it's easy. But what if the field is say, GF(2,3,x^3+x+1)? Suppose, for example, I entered: ``` r:=rand(8): G:=GF(2,3,x^3+x+1): M:=Matrix(3,3,(i,j)->G[ConvertIn](x^r())); ``` How would I invert M (over the field G); multiply M by another matrix, and so on? Can I do this with the Domains package? Thanks, Alasdair

## Plotting directly to file...

I want to use command line maple to plot a function and capture its graph directly to a *.gif file without displaying it. How do I do it? I've gotten Matlab to do it, but can't seem to find the necessary syntax in Maple. Thanks, Eddie

## Can Maple do a 3-D graph of an animated sphere in ...

I have been tasked with the following job by my former advisor, and I have not be able to find an answer as of yet: can Maple make a 3-D plot of a cube with a moving sphere or ball inside of it. The animation of the sphere would be as follow: moving along each of the three major axis of the graph to highlight them. The animated sphere would also have to move continuously through the axis (or discretely over such small increments as to appear to be moving continuously.) Can anyone help me with this? Thanks in advance. Chris W.

## Maple T.A. 2.5 can be started when the Fecora Core...

I installed Maple T.A. 2.5 on Fecora Core 4, and it can be started on the XWindow. I added the command "MapleTA_installed_dir/bin/mapleta.sh start" at the buttom of the script /etc/rc.d/rc.local, and I hopeed Maple T.A. service can be started when I reboot the system. But It doesn't work !! That means I have to go to the front of the machine, then I can start Maple T.A. service. It's very inconvenient for me. The following message is came from logs/mapleta.out loading... Root Empty Class loading... Maple T.A. Demonstration Class Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

## how to get maple to break down the problem into st...

other post I am trying to solve the following problem and many others like it but showing how to do it step by step. f := [z = (1+y+y^2-y^3)/(1-y)^3] I am to pick a value for z between 0.601 and 0.899, I chose 0.8 since its as close to a solid number as I could get. z := `0.8` eval(f) z := 0.8 eval(f) hmmm still not solving or breaking down the problem, just showing my the problem with 0.8 in place of z solve(f)

## Sudoku...

Has anyone written a MAPLE program to solve sudoku puzzles?

## problem with kernel connection...

Hi, as I did not receive a response to my first post I renew it with more details. I use Maple10 for Prof. under the operating system XP pro. My Maple is out of order because my "kernel connection is not available" and Maple is closed by "mserver.exe"; yet my firewalls are stopped when I open Maple. Before this problem Maple did'nt find the dll:"libgmp-3.dll". I reinstalled Maple but the problem is the same. What can I do? Thanks

## Maple Install/Version Info...

I am a new-to-ubuntu (edubuntu) user, wondering, which version of maple should I purchase to install? SuSE? Mandrake? Hmm, I'm going to qualify my inability to find the answer own my own with, "i tried really hard to do it on my own teach." Thanks in advance.

## 3D Plotting...

This may be a very easy question to answer. But I can't get maple to plot a function. What I need is a 3D plot of: v2 vs epsilon vs r With the variable k varying between 1 and 2, and r varying between 1 and 250. but every time I try to plot, the program gives an error "Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct". But if you manually calculate v2 and epsilon using the values given, they wrk out fine. I'm sure I'm just not doing something right but I can't seem to figure out what.

## Getting output to look exactly as I want it....

What if, for display purposes, you wish the output of an execution group to look exactly a certain way. For example, I am trying to get the output to look exactly like
The use of single quotes doesn't seem to do the trick.

## satisfiability of linear inequalities system...

Hi every body,
I am new in Maple, I am intend to use Maple in order to check the satisfiability of linear inequalities system which mean to determine of there is exist a solution for a set of linear inequalities system. For example for:
x>=2y, x<=2y, x=y, x>0, y>0
there is no solution. I use this in my thesis research (Actually nequalities system represnt the constraints of my system)
How can I use Maple for this issue? can any one give me an example for the above constraints? Thanks in advanced
