I have an array of 2 vectors in a do loop, the vectors being i (path number) and j (time).

i goes from 0 to ntime, and j goes from 1 to ntime+1.

The array is called Spot[i][j] and i need to find the average of this array but dont know how.

Any help would be appreciated!

Thanks!

Hello

Can anyone help me  please in how to compute the Big oh in this example?

since I didn't get any exact solution.

The AddVertex command (in GraphTheory) does not seem to copy any attributes that were set in the original graph.

with(GraphTheory):
G := CompleteGraph(5):
SetGraphAttribute(G,"graphAtt" = 1);
SetVertexAttribute(G,1,"vertexAtt" = 1);
SetEdgeAttribute(G,{1,2},"edgeAtt" = 1);
H := AddVertex(G,6):
GetGraphAttribute(H,"graphAtt");

Hi guys,

I would be ever so grateful if someone could asssist me with the following matter.

I am trying to integrate the following expression but maple does not seem to be able to do it directly

Int((1/(2*Pi) + Q* cos(k*phi))^2/ (1+ beta^2*((1/(2*Pi)) + Q* cos(k*phi) )^2),phi=-Pi..Pi);

So I convert the expression to an exponential form as follows and evaluate that

 numerator:=(1/2/Pi+Q*(1/2*exp(I*k*phi...

I just want to know how i could label the expressions that are generated by executing the loop,

like A1 = .....

A2= .....

If you see the file above , the for loop gives out several expressions in terms of c and t , the equations generated are correct but i want to give each expression a label like A1,A2,A3 when the output is generated

I am trying to make substitutions into a matrix using the subs() command, but it does not work.

for example

with(linalg):
A:= matrix([[a,b,c],[d,e,f]]):
B:=subs[inplace](a=1/L,b=-1/L,c=1,d=-1/L,e=L,f=1,A);

Back when I was working at the University of Waterloo, I found several copies of a VHS tape sitting on a dusty bookshelf full of old Maple boxes and manuals. The tape's cover had a line drawing of Issac Newton on it and the title "Maple V: The Future of Mathematics".

There was...

can any one please help me to know the no.of default iterations in isprime() function.

Thanks in advance.

Maple 15 will soon be released (looks like sometime in April based on the last two relese dates).  It also looks like Maplesoft, recently, has settled into a happy release date schedule of April and October where we can most likely expect a major release or update to be available. 

It seems ironic that the even releases of Maple seem to be the most successful.  Maple 10 was more so than Maple 11 but probably due to it's long 2 year stay before...

Dear all,

I've got a Vector,

>V:=<xt[1, 1]*xt[1, 2]*alpha>;

and what I want to get is the elements in V which has xt[2,2]. In this case, <NULL> is what I am looking for.

I tried the following line:
> select(has,V,xt[2,2]);
     The result is Vector(1, {(1) = NULL});
when I tried
> select(has,V[1],xt[2,2]);
     The result is 1.
I have no idea where this

When I use pdsolve to solve a system of PDEs, and tell it to use HINT='*', does the solution I get ONLY contain those obtainable by separation of variables, or does it use separation of variables as a starting point and deliver the general solution? And how can I tell?

Hello,

I make an simple animation as the figure illustrated, which the key codes were learned from Mr. Robert Israel a few days ago in one thread. Now I want to let the rectangle motionless when the circle rotating in the rectangle for a special use. Is there any way to achieve it? 

Good Night.

I have problem when i am using ODE, because i have an error : (in plots/odeplot) curve is not fully specified in terms of the ODE solution, found additional unknowns {x3(t)}

I do not know how I can 

Hello everyone,

I need to create a 3d plot, but color the surface depending on the function's sign, say red for positive values, green for negative. How can I do that?

Thank you,
