Is there a way to select multiple entries in a ListBox component? 

Hi,

    I'm trying to get a component to perform a Fractional Derivative in MapleSim to use in a multibody simulation (as a spring-dash pot component). However, I'm stumped by trying to get the fracdiff function past the custom component code.

• When set to series, the fractional derivative is only accurate near the estimated about point
• When set to LaPlace, it's impossible to perform the transform...

I have a problem.

I solved a problem, but i like to get one solution for one variable.

i send my project.

help me please.21-07-2011_-ecuacion.mw

Dear guys

In my program I have a loop and after some calculation I want to write the results. I use:

" writedata("D:\\arvin\\bao-cmb-h.txt", convert(T, array), float);"

but maple give me an error:

" Error, (in convert/list) object too large "

how can I write my data?

Thanks.

I'm developing an application that I'd like to use elements of an array as parameters in MapleSim components - is there a way to use Maple arrays/vectors in MapleSim?

Also is there a way to open a file and read its contents (data) as the starting point (parameter set) for a MapleSim simulation?

Hi Dr. Kamel Boughrara,

I have a question,  I know phi = B*A, but in code i can't understand a part of it, can you kindly explain it in engineering terms.  

kindly see the attach file for phi.

Second question

why e-->sum(factor(e(t)),n=1..100), wht this means, 

Hi guys,

I am working on the following pde

m₀=-Bw_ssss+(F_t-Bw_ss²)_s(w_s+r_s⁰)+(F_t-Bw_ss²)w_ss+q

where

F_t=EAe+T₀+p_wgPiD_o² (H_w-z)/4-p_mgPiD_i² (H_m-z)/4

Hi Dr. Kamel Boughrara,

I have question regrding the analytical solution in section 3.3,  I am attaching a file.   Question is regarding  the programming you did, does it has any effect on the solution.  Because i tried to change the values for p, and other variables but could't see the effect.

Also wht the following variable means;

Hi i´m writing a paper about math and i use maple 10 and M. Word 2007 for it, i started with a Laptop with Windows 7 and when i finished it, i open the archive in a desk computer having the same especifications  i notice that the images of ecuations were altered changing "+" and "-" for "C´s" and "K´s", i tried a lot of computers with others especifications and my problem still the same, i changed the format and other stuff but i can´t...

Hi:

I am running a home network, XP and Maple 11 on the old computer, Win 7 and single-user Maple 15 on the new.

It took a long time, but I finally got a wireless network running, so that Win7 on the new computer can open and access all the files on the old computer.

But when I run Maple15 on the new computer and try to open an old computer file, Maple 15 cannot see the old computer or any of its directories, even though it has a "network" tab on the "open" command.

If you create a Maplet using the Maplet builder, how can you insert it into your worksheet ? ... e.g. having a hyperlink or button which when clicked runs your Maplet ?

I'm using maple 13.

The expression that I paste below is quite large and subsequent expressions are also swelling. This is causing maple to slow down and in some instances I get a message saying the kernel has disconnected (maple just times out) I want a way to programmatically reduce the size of the output. I have tried simplify(expr,size) and this has helped some. I don't want to use simplify(expr,symbolic) because of the presence of the square roots. Is there...
