Hi everybody, 

Only weights of type "numeric" can be used in a weighted graph (package GraphTheory) .
Is it possible to bypass this limitation and affect an infinite weight to an edge ?
If not possible, does it exist some "highest numeric value" in Maple I could use instead ?
(the trick of a very high value doesn't suit me)

Subsidiary question : is it possible to change the printing format for those weights ?
For instance   GraphTheory:-SetEdgeWeight(MyGraph, MyEdge, 123.4) plots the value 123 on edfe MyEdge

Thanks in advance

Hey there!

I wonder how i can solve the following using maple.

I got an equation containting 2 variables; x and T.

I want to plot x versus T, with the range of T from 300 to 800.

How can I do this? 

This is the formula I am talking about:

Thanks in advance!

Kind regards,

Geard

I have the following expression:

expand((((o * (((h * h - h * v) * (a * h - a * v) * h * h * h * h * a * a * h - h * h * h * a * a * h * o * (h * h - h * v) * (a * h - a * v)) * a * a * h * h * h * h * h - h * h * h * a * a * h * h * h * h * h * a * a * h * (a * h - a * o) * (h * h - h * v) * (h - v)) * h * a * a * h * h * h * h * a * a * h * a * a * h * h * h * h * h - h * h * h * a * a * h * h * h * h * h * a * a * h * a * a * h * h * h * h * h * ((v * (a * h - a * v) * h * h * h * a * a * h - h * a * a * h * (h * h - h * v) * v * (a * h - a * v)) * a * a * h * h * h * h * h - h * a * a * h * h * h * h * a * a * h * (a * h - a * o) * (v * h * h * h - h * (h * h - h * v) * v))) * h * a * a * h * h * a * a * h * a * a * h * h - h * h * h * a * a * h * h * h * h * h * a * a * h * a * a * h * h * h * h * h * h * a * a * h * h * h * h * a * a * h * a * a * h * h * h * h * h * o * (((a * h - a * v) * h * a * a * h - a * a * h * o * (a * h - a * v)) * a * a * h * h - a * a * h * h * a * a * h * (a * h - a * o) * (h - v))) * h * h * a * a * h * h * h * h * a * a * h * a * a * h * h * h * h * h - h * h * h * a * a * h * h * h * h * h * a * a * h * a * a * h * h * h * h * h * h * a * a * h * h * h * h * a * a * h * a * a * h * h * h * h * h * h * a * a * h * h * a * a * h * a * a * h * h * (o * (v * (a * h - a * v) * h * h * h * a * a * h - h * a * a * h * (h * h - h * v) * v * (a * h - a * v)) * a * a * h * h * h * h * h - h * a * a * h * h * h * h * a * a * h * (a * h - a * o) * (v * v * h * h * h - h * (h * h - h * v) * v * v))) );

When I tun it through the Maple GUI I get this result:

-2*a^23*h^40*o*v^2+2*a^23*h^40*v^3

This is also what Mathematica gives me. However, if I run it through the Maple command line I get this result:

-a^77*h^97*o*v^2+a^77*h^97*v^3-a^23*h^40*o*v^2+a^23*h^40*v^3

Why are the results different?

Greetings,

i have a problem working with a list of equations. The background for the whole thing is simulating the movement of 4 astronomical bodies with Newtons equation. Currently i have a list which looks like this (read x(1,1) as x-coordinate body 1 time =1):

[ x(1,1)=1,12312,y(1,1)=2,3123,z(1,1)=4,141,...,x(1,n)=5,0102,y(1,n)=0,912,z(1,n)=8,1232,...,x(4,n)=5,92y(4,n)=1,656,z(4,n)=3,141]

so i basically have all the information about where the bodies are.

I want to use this information to create a 3D-pointplot. I know that the point plot requires a special input form ( {[x(1,1),y(1,1),z(1,1],[x(1,2),y(1,2),z(1,2)].....} ), but i alread have managed to convert my original list accordingly. However, i cannot use this new list for pointplot because it contains equations and not simple values.

So how do i get from a list as shown above to a list which contains merely the numeric values?

Hello,

I know that it is possible to conduct the dynamics of multibody systems with MapleSim. But, is it possible to conduct only the kinematics ? Would it be possible to share a example where only the kinematics is conducted with MapleSim?

Thank you for your help.

Hi I was wondering if anyone can help me with the following procedure, i am trying to write a procedure that can encrypt/decrypt messages encrypted using the method of ELGamal my current procedure runs but it takes too long to compute, and it can only decrypt.
 

My procedure is as follows:

my procedure for part c is as follows it seems to run but it takes a long time to carry out the procedure when i try to decrypt.

               Elgamal := proc (ciphy, hkt, p, a, b)
               local i, icdarray, s, q;
                 icdarray := Array(5 .. 388);
                   for i from 5 to 388 do 
                   s := ciphy[i];
                   q := `mod`(1/hkt^proc3(a, b, p), p);
                   icdarray[i] := s*q;
                   end do;
                   return convert(icdarray, bytes);
                  end proc;

where proc3 is as follows

                      proc3 := proc (alpha, beta, p)
                   local k, R, i, j, N, A, t;
               Description "baby step giant step procedure";
                 N := floor(sqrt(p-1))+1;
                 A := Array(0 .. N);
                 for j from 0 to N do
                 A[j] := `mod`(alpha&^j, p);
                end do;
          for i from 0 to N do
             t := `mod`(beta*alpha&^(-N*i), p);
            for k from 0 to N do
            if t = A[k]
           then return k+N*i;
         end if; 
         end do; 
           end do; 
         end proc;

I've made a system of two equations:

eq1:= x^2+y^2=0.314

eq2:= y=0.05180967688x

The first is a circle while the second is a line. I use the command fsolve in order to get the intersection and i get:

{x=0.5596,y=0.02899}

I need to use these results as the coordinates of a pointplot, how can i do it? Is there a way to isolate x and y?

Thanks

Hello everyone, I was trying to plot graph for some functions but its just plotting one plot. Anyone with useful information please.

So here's a problem.  We have two of the same commands that operate differently in and outside the plots package. 

changecoords([x, y, z], [x, y, z], spherical, [r, theta, phi])
                        [r*sin(phi)*cos(theta), r*sin(phi)*sin(theta), r*cos(phi)]
with(plots):
changecoords([x, y, z], [x, y, z], spherical, [r, theta, phi])
Error, (in plots/changecoords) changecoords does not accept plot options or other additional arguments

How can we get around that problem?

I ploted two functions on 2D plane. I need it for my paper and I need the part of the functions under y=x line. Is there a way I can show only the functions below the red line. I attached the maple file. Thank you.
