When rotating any 3dplot, for axes=boxed, how can I stop the tickmark axes from jumping around to different edges of the box?

 

Can someone give a an example what the choices in tools/options/precision/ Digit Elision or term elision are good for ? The help page is unclear to me:

Hi (working with maple since yesterday, so question might be elementary) I have an ODE system with functions x(t,k),y(t,k), t is the independent variable, k is a parameter, as well as initial conditions. What I am aiming at is a 3-d plot of the _derivate_ d/dt x(t,k) of the first solution of the system, and t and k as horizontal axes.

i have 3 equations as follows: x1+x2+x3 = m (where m is any constant. it can be taken 1 for finding solution) -3*x1+4*x1^3-3*x2+4*x2^3-3*x3+4*x3^3 = 0 5*x1-20*x1^3+16*x1^5+5*x2-20*x2^3+16*x2^5+5*x3-20*x3^3+16*x3^5 = 0 0

Hello,

this is the first time I am using the command line for Maple.I have a few questions,

1. How do I change my current directory?

I tried with currentdir() but with no success.If my dir is E:\Work ,how do I change it?

2. How to execute a *.mpl?

I tried cmaple.exe <*.mpl> but again no success.

 

I am using Maple13 by the way.

 

Any help is golden.

 

Best regards

I have a big list in Maple named A with 324 elements. I want to change one of the elements of that. For Example  I want to say

A[274]:=xi=xj;But I receive error which says:Error, assigning to a long list, please use Arrays.

How do I create a multiplication table for congruence classes? For example, I want to multiply x+x+1 by x+1 in Z₂[x]/(x+x+1)

Hello,

I found this on a website:

------------------------------------------------------------------------------------------------------------------

To clear all variables in Maple and restart without having to reload the application, enter:

restart;

This will clear all values, unload all packages, and reinitialize Maple. However, this command will not free up memory previously allocated to Maple; consequently, when doing large jobs, the only way to improve speed is to exit and restart Maple.

------------------------------------------------------------------------------------------------------------------

Does this mean I can't clear any variables from memory at all without closing Maple?

In Matlab all you have to do is:

and that will clear the variable x from memory (you can see that the amount of memory allocated to Matlab goes down if you look at the windows task manager)

 

In Maple when I clear the variable x by applying the command:

the amount of memory allocated to maple remains the same.

 

I'm hoping that that website was wrong and there is a way around this because being able to clear a huge variable that's only needed for the initial stages of a long computation is extremely important - any software should be able to do this.

Hi. I recently turned over to maple 13, after using TI InterActive! for 2 years. But i am having som problems working with vector functions in maple. Here is a link to the PDF file with the exercise in TI: https://docs.google.com/fileview?id=0Bx5y79IuSOVJNTAxNmJmODAtOGY3OC00NWRhLWI0ZTgtMzBmOWJhMzYzMDMw&hl=en It's when i reach "Opgave 2d" that i get into trouble.. when i differentiate the r(t) function it just gives me an error.. "non-algebraic expressions cannot be differentiated" And im just wondering wether there are other functions in maple to differentiate vector functions?

Dear All :

  I have a ODE equation system like this:

eqns := 1.00011000*10^(-7)*(diff(v[gs](t), t))-1.000*10^(-12)*(diff(v[ds](t), t))+v[gs](t)+1.000*10^(-18)*(diff(v[gs](t), t, t))+5.00*10^(-19)*(diff(v[ds](t), t, t)) = 12, 2.900*10^(-18)*(diff(v[ds](t), t, t))+5.00*10^(-7)*(diff(v[gs](t), t))+6.00*10^(-19)*(diff(v[gs](t), t, t))+v[ds](t) = 24
 

ics := v[gs](0) = 3.5, v[ds](0) = `#msub(mi("V"),mo("in",fontweight = "bold"))`

Dear all,

I was wondering if there is any simple way in maple which could do the following:

given a polynomial (over the reals), return a list or set with all its (maybe monic) factors.

That's not exacly what the 'factor' command does.

 

As an example, given the polynomial (x+1)*(x+2)^2, I would like to get something like:

{1, x+1, x+2, (x+2)^2, (x+1)*(x+2), (x+1)*(x+2)^2}

 

Do you know if this is possible in a somewhat straightforward way?

 

Many thanks in advance for your time..

I have an array of 25 values and need to plot a graph with these values

Hi

I have some 3d plots with colors that I would like to export to a vector format such as eps or ps. At the end I will use it as a eps picture in a latex document so if it is possible to export directly to vectorized eps.

I have tried to used to export feature but this simply export it to something that look like a very hard compressed jpeg picture.

Does anyone know how to do this?

 

Thanks in advance

Regards Brian

hi, for example i have this equation:

i need to factorise it so that i have all of the eta^2*g^2 terms together, can somebody pls show me.

 

thank you
