I need to search for primitive polynomials of degree n over finite fields GF(q), where q is a PRIME POWER. I have major difficulties doing that, especially when I wish to fix one of the coefficients of the polynomial. On the other hand, polynomials over GF(p) pose no problem. Does anybody have any experience in this? PLEASE HELP!

Hi there everyone.
I have recently been trying to plot fourier transforms.
After taking the fourier transform of a particular function of the time domain for example a sinusoid. I get a sum of terms each with a translated Dirac function.
When I try and plot the series of Dirac functions it doesnt work in the sense that there is nothing displayed. The plot initializes but there are no Dirac functions.
Is there a way to plot Dirac Functions?
thanks

Dear Maple Users,
I have the following problem:
How to find the best-fitted function P(x,y) = ax+by+cxy+d to the following data:
i= 0, 1, 2, 3, 4 , 5 , 6 , 7
xi= 150, 152, 154, 156, 156, 157, 158, 158
yi= 134, 136, 106, 61, 90, 124, 41, 135
I know that in Maple functions that can solve interpolation and approximation problems with one variable are implemented. But how to solve the problem with two variables?
Best regards,

Hi to everybody
I'm a new user of Maple
How can I solve this system?

hi everyone ,
please help me to sort out this problem ...
suppose i have a matrix
1 2 3
? 2 ?
2 1 6
where ? are unknown values .
what i want to do is to "Fill in the missing values by the respective attribute means. " How i will do it matlab?
please help me as soon as possible ...

I have been experimenting with overloading existing Maple functions by creating an appropriate package, as described in the "overload" help. It works fine in general.
I was hoping to change the definition of `abs` on type Vector to be sqrt(V . V) in this way, but the change does not work because `abs` already has an alternative definition on this datatype and it seems that built in functions take precedence over overload versions that one has added. Is there any way of achieving this?
Grateful for any pointers.

Maple usually has white background and red font. How to set font black and background color in light grey?
Should I use "Format"--"Styles"? But why each time when I build new file I lost the previous style setting?

weights in Statistics[NonlinearFit] within M10:

what does that do exactly - stupid me can not find from the help

saying "weights = Vector -- Provide weights for the data points"

Does that mean the points are weighted (i e the count multiple)

or does it do (fct(x_i) - approx(x_i) )^2 / weight_i or what?

If i save a sheet in M10 and open it then it shows tildes

dispite having interface( showassumed = 0 ) in my ini file.

In M9.5 that was ok (using WIN ME in both cases, classical

interface of course ... and having asumptions in the sheet)

How this ugly behaviour can be avoided?

Trying to calculate the determinant of matrix A i have to add extra details to the function (integer) to get result (for example): Det(A) - does not work for me, but - Det(A) mod 10000 (or 10^n); - does and gives the result (honestly it took me a while to get it clear, i mean to get Det(A) work). I think it's not the way it is supposed to work. In help it's simply clarified that Det(A) function should give the result of determinant of matrix A, without any additional integers like mod :/. I can't figure out this riddle.. (i've started using maple 3weeks ago, and mostly for algebra and geometry). Any help pls? Do i have to change any settings? Tnx, in advance =).

I want to know how to send mails to multiple email addresses using PHP code.
Thanks.

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!

pls check the attached worksheet ... any reason for that behaviour?

PS: not attached due to some oddity of the forum software,

"Error attaching file 102_strangeRoot.mws: exceeds maximum file size"

so take it from http://www.axelvogt.de/maplekram/strangeRoot.mws

(or *.zip if perfered, it is below 4 kB anyway ...)

I'm trying to figure out how to fit the data below to a curve of the form:
a+b*sin[(pi*x)/6-c]
How do can I do this in Maple 10?

2,47.2
3,53.7
4,60.9
5,70.5
6,82.1
7,88.0

9,77.4
10,66.0
11,51.5
12,44.1

Is it possible with Maple 10 to change a document so that in the middle, there are two columns? One might imagine having some text describing how data was gathered where the text is spread over the usual six inches or so. Reading on down the document, the style might change to two columns: a graph of the data in the right column and comments on the data in the left. After this, the document could revert to the normal six inch, full line text.
Did I not see something such as this in a demo at the Maple Summer Conference?
