I have recently upgraded to Maple 14, and I can no longer cut and paste syntax between components when I am editing their properties.  Is this normal, or do I have to adjust a setting?

Thanks,

Phil

example.7.mwI have a question for a long time.

For some dynamic systems, I want to extract the matrices or the transfer functions which maple had yielded as a table. The table contains matrices or transfer function.

I want to extract them for other purposes, for example,using transfer function to plot its step response.

Now, is there any way to do this without retyping them manually? Becouse...

Hello, 

I'd like to modify the form of this expression

To manage to have this form.

I have the function,

f:=5000/(1+99*exp((-0.8*t)));

and I would like to find it's inverse....how can I do this?

hi

I want to get points from plot for example I have a graph like y=x but I do not know its function I want to get just some points from that like [1,1] ,[2,2] and the others but I dont know how?

the second problem which I have is I cannot show points like [1,2,2] by plot,it shows just 2D not 3D points.

I mean x=1,y=2,z=2

plot shows just 2D like x=1,y=2

thanks for your attention.

Hello,

Is there a Maple procedure that generates all possible partitions of a given set? For example, for the set {1,2,3} it should give {1,2,3}, {1,{2,3}}, {2,{1,3}}, {3,{1,2}}, {{1,2,3}}.

If not, how could I write one?

Thank you!

Consider the following simple calculation with Ore algebras:

DA:=Ore_algebra[skew_algebra](euler=[theta,z]):
Ore_algebra[skew_power](sqrt(3)*theta,2,DA);
Error, (in Ore_algebra:-skew_power) skew polynomial must be member of the algebra

The error is due to the square root which is not recognized as a member of the algebra even though it is only a number. There seems to be no option to remedy this issue. Is there another solution ?

I made a model in MapleSim(Fig 1).

Here is the custom element named 'FcF' among the model. Its equation is defined as Fig 2.

I analyses
the model in Maple, the part related with the equation of FcF is shown
as Fig 3.

 I want to solve  matr.mw  for matrix A and B. Although it has 7 equations and 7 unknown parameters, but  doesnt have any result

question.mwWhen I sloving an exercise in my textbook using maple,I had a difficult.

First,I write the differential equation, deq:=[...];then using command,sys1:=DiffEquation(...);I want to get the system transfer function,so I use command tf:=TransferFunction(sys1),but it returns an error[Error, (in DynamicSystems:-TransferFunction) cannot handle input with frequency variable, s].

Then,since TransferFunction...

My problem that i just simlply can`t start Maple 12 under Windows 7 x64 in classic worksheet mode.

I like that much and i tried the suggested maplew.exe -cw but i got the same fancy window what i get starting just maplew.exe.

I need help and thank you.

hi, i have an equation and i cant simplify it. i claculate with hand and i know the answer but with maple i cant give answer.

       aa:= sin(theta + tao s) cos(d s) + p d cos(theta + tao s) sin(d s)

        bb:=  sin(theta + tao s) sin(ds) - p d cos(theta + tao s) cos(d s)
                 cc:=         ...

In a series of posts now imported to the Maplesoft blog (starting here), I have been talking about pseudo-random number sequences, but since part of what kicked off this series was a paper on true random number generation (with LASERS!) I thought I would share some routines I wrote that alllow you to use the two main true random number sources available on the web (neither using lasers, sadly).

I spent this past week preparing a Webex presentation to a client who was interested in using Maple for a physics course in chaos. Of the two texts selected for the course, I had one on my own bookshelf. So I scanned Steven Strogatz' text Nonlinear Dynamics and Chaos (Addison Wesley, 1994) for topics that would profit from investigation with Maple.

Hi,

I am not very familiar with maple but have a problem that is probably very easy for an expert. I have the coordinates of three variables, but no specific function of it. I want to create a 3d graph with these coordinates but do not know how. I have done it before with a specific function, but do not know how to do it with solely the coordinates, I work with Maple 12. Could somebody please help me, it is very important for me! thanks in advance,
