For a given galois field, suppose there is such a polynomial function mapping from GF(q) to GF(q):
x^(q+m)+x^(q+m-1)+x^(q+m-2)+...+x^(1).
I can use x^q-x=0 to "reduce" it to such the following form:
x^(q-1)+x^(q-2)+x^(q-3)+...+x^(1)

now, the problem is whether this is the only method (x^q-x=0) to reduce a polynomial function mapping from GF(q) to GF(q)?

Thanks a lot.

Maple and Solidworks...

Hi, what are possible ways to exchange data between Maple and solidworks ? Assume i have a Matrix -created in Maple- that contains 3d data for a CAD model. Is it possible to pass this data to solidworks ?

 

Thanks

# I want to maximize the following function:
((2*c+a-d-2*b)*delta-(1/2)*c+(1/2)*d-b+a)^2/(9*b-9*a):

# under this constraints:
b-a >= c-d:
c-d-b+a <= (2*b-a-2*c+d)*delta:
(2*b-a-2*c+d)*delta <= 2*b-2*a-2*c+2*d:
a = x[min] .. b:
c = d .. y[max]:

# and I have the following values:
x[max] := 10:
x[min] := 0:
y[max] := 10:
y[min] := 0:
delta := 1:
b:=2:
d:=5:

# I have tried to find the maximum with NLPSolve and the option 'maximize':

IsDefinite...

March 20 2009 SandorSzabo 597

I have 5 matrices, Hmatrix[1], and so on.

I can test

map(IsDefinite,Hmatrix)

Maple gives the 5 answers.

How can I test using map the negative_semidefinite property?

Thanks.

improper integral question...

Hi how to calculate improper integrals with the tutors and (if possible) showing the procedure step by step? Let’s take my homework as an example. Calculate: > int(1/((1+x^2)*(1+4*x^2)), x = 0 .. infinity);  

Hi, is there a detailed list of differences between those 3 product lines of Maple ? Maybe additional packages for the pro version  ? Are worksheets, created with one version, completely compatible to other ?

 

Thanks

Hi,

 

I am kind of new with using maple, and I am hoping that someone can give me some help on nonlinear curve fitting.  I checked out the help topics, and I thought that I had put everything in correctly, as per the help file.  However when I try to do a fit to data, nothing is returned.  Here is what I have input:

 

So, I have r^3=1/64. I need help finding r

Nonlinear DE...

March 18 2009 tridran 4

Hi all, I'm not good at maple, so need a help from experts. I'm using Maple v.12. -part of the code- ... de2:= # Nonlinear DE is here # ics:= X(0) = 1, (D(X))(0) = 1; sol:= dsolve({de2, ics}, numeric, method = rkf45); (or sol := dsolve({de2, ics}, x(t), numeric, stiff = true, range = 0 .. 200);) Error, (in f) unable to store '1.0000000024691*{1.}^2+2000010000.' when datatype=float[8] -end of the code- As you see above, It's a simple process to solve DE. so most of the DE, like (1) below, is solved very well through the code. But my case is (2). I could see error msg as you see above.

cannot run this maple...

Good day, I cannot run this maple, why?

I need help!

I'm trying to plot a sphere, and then shade-in the bottom one-third of it.  Is that possible?

Also, I then need to plot a sphere with 8 approximating disks.

Does anyone have any ideas of how to do these?

3D Plot...

March 17 2009 tbasket 476
I have a Matrix O[n,m]:=Value with n:=1..10 and m:=1..10 How can I present the values in a 3D plot with x->n Y->m and Z->Value. One time I want to make a histogramm out of it and in a second case just connect them to a surface How can I do that Thank you very much in advance!

plot problem...

March 17 2009 Oliver K 1116

Hi,

have a look at this plot, i'm using standard worksheet (in classic this problem doesn't exist). 

plot(sin(x),x=-5..5,tickmarks=[default,20]);

Instead of -for example- 0,5 i want decimal points 0.5

Playing with the tickmarks option would do the trick, but a "global switch" would be better.

What to do ?

Hello everybody, I was wondering, is there a way to call procedures from a different worksheet? I am writing a big procedure which calls many smaller ones and that would be really clearer if I keep them in a different worksheet.. Thanks a lot in advance..
