Hello guys ,

I found critical points for a 3-D dynamical system (x,y,z) and m which in general is not constant (m(z/y) is a function of z.y, when i calculate eigenvalue for every critical point ,the maple assume m constant . how i find eigenvalues for general m which is not constant and is a function of z/y .

Thank You

Dear Maple experts,

I have a function f  depending on three variables a,b,c i.e.   f(a,b,c).

I have to find the df/da (differentiation  with respect to a) and then solve for variable a in terms of variables b and c to make the f(a,b,c) into f(b,c). 

However, I am not able to find the symbolic relation from df/da to represent variable a interms of variables b and c because the solve(df/da, a) is...

A beam of neutrons bombards a reactor's wall. Consider the motion of the neutrons as a random walk on the (x,y) plane.

The neutrons then have to comply with the following conditions:

1. Only four directions of motion are possible (left, right, up or down).

in following coding
final equations Exp1 ,Exp2, Exp3, Exp4 depends on X2 and X3, but in these equations I have introduced certain equations which are also depending on X2 and X3,like fccL[Ni, Si] etc, but that dependend variable is counted as different variable while plotting the function or evaluating it Help me please

Hello all.

            I want to execute a particular section of my legthy code, after certain lines I want that let Maple not execute further. It could be a possibility that after those ceratin line I may execute my code further. I dont want to comment those lines as some later stage I may use them again. Is there any command which can fulfill my purpose.

Many thanks in advance.

Hi all,

I am running xmaple via linux, version 17.

This is on a Unbuntu OS X64 with i7 940X, and 4G RAM.

Hi,

Could someone check, what it is wrong?.

I have tried to use fsolve inside module in startup code.

I will be appreciated.

Hi, how can I make a prodecure in Maple 16 that takes a function as a paremter and then manipulates with it?

e.g

Test := proc(f)
return f(10):
end proc 

And I can then run Test(f(x)) and get f(10) back?

Thanks 

Hi,

     For some reason Maple won't compute the eigenvalues to my matrix, which contains complex numbers and 1 symbolic parameter (h). heres the code

elements:=[1.+0.*I, -0.1e-5-0.4e-4*I, 0.2e-3+0.*I, -1.*10^(-7)-0.4e-5*I, -0.1e-5-0.4e-4*I, -0.1e-2+0.2e-4*I, -3.*10^(-7)+0.3e-4*I, -2.-0.2e-5*I, 0.3e-3+0.*I, -3.*10^(-7)+0.3e-4*I, 1.+0.*I, 6.*10^(-7)-0.2e-5*I, -1.*10^(-7)-0.4e-5*I, -2.-0.2e-5*I, 6.*10^(-7)-0.2e-5*I, -0.3e-4-9.*10^(-7)*I]:

Hello,

On a mechanical system that I could put in the classic form M*diff (x, t, 2) + K*x (t) = 0, I would like to calculate the angular frequencies.The methods that I know are:
- Calculate the solutions of the equation det (K-omega ^ 2 * M) = 0
- Or calculate the solutions of the equation det (M-1K-omega ^ 2 * I) = 0
- Or directly determine the eigenvalues ​​of M-1K using functions already created in Maple for example.

Hi,

I am trying to solve an ODE with Maple:

hi friends i have to plot multiple graph but problme is am not able to show curve instead of points. My input is in points but i want output in form of curve or points joining with lines. beside this i also want my both curves to be of different color so it can b highlihted that i have plotted two curves. I tried but am not able to change shape of points Graph.mw

I have following commands at Maple:

>T:={[{a,b,c,d}, table([a=0,b=0,c=0,d=0]),8],
[{a,b,c,d},table([a=6,b=1,c=2,d=0]),8],
[{a,b,c,d},table([a=6,b=5,c=5,d=7]),8],
[{a,b,c,d},table([a=7,b=1,c=2,d=0]),8],
[{a,b,c,d},table([a=8,b=8,c=8,d=8]),8]};
 
> member([{a,b,c,d},table([a=0,b=0,c=0,d=0]),8],T);

I want that it should respond `true` as the given special list is a member of the set T, but it gives me `false`. Help please.
