The following error occurred when I simulate a build-in model, anyone could help me to solve this problem? Thanks first

Hi, as I can't manage to copy and paste on mapleprimes, I would be glad to get a hint ...

Hello,
I am looking here for a tutor, that can help me doing some Maple V (5) programming.
I am a mathematic student and we use Maple programming.
I will be happy to pay a small amount of money for each exercice you help me doing,

if anyone is interested, please contact me here.

(The procedures that we usually have to write are for example:
 Newton-Raphson Method, Chebyshev Polynomial,...  I don't think it is hard for you.
Thank you very time for your time and your help.

guys i got this error permanently for everything , can anyone help me ?

I'm new to mapleprimers and if I make some mistakes I apologize. 

The problem I ran and on which I ask for help is that the command of maple latex I results in latex only the result of an arithmetic expression and the expression does not translate into latex itself. for example, the command latex (3 + 2) I 5 and not as a result from the translation in latex of 3 + 2. I also tried using the command inetrt form but did not succeed, I tried it with the quotes '' and even succeed. I also tried it with double quotes and with simple expressions funzioa eg latex ("(3 + 2) * 5") from me as a result `` (3 + 2) * 5 '' but with more complex expressions: eg. latex("\""(2+1/(5))^(0)+(6/(9)*(((83-8)/(90))-15/(10)+(3/(9))/(2)) -6/(9))/(75/(100)*12/(9))"''") mi da 

Error, Got internal error in Typesetting:-Parse:-Postprocess : "internal error: invalid object ""

Thanking for the help, Best regards

Hi all,

How to build an uneven ground by MapleSim?

I want simulation a car runnung on this uneven ground.

Is there any method , proposal , orientation, or any thing can help me

Thank you

Hi all,

I met a problem while using the MapleSim7.

When I increase the plot points (which can be modeified in the setting tab) to get more accurate solution,

MapleSim does not show the simulation results (ex. graph) even though the simulation has finished.

MapleSim message only says "Done Simulating", but does not show the results.

When I set plot points "10000", I could obtain the results. However when I set "30000" for plot points, 

I couldn't get results.

What is the problem and how can I obtain the results with many number of plot points?

Hello, I would like to customize the context menu in Maple 18 and looking for a way, to convert 2-D expressions to classical maple input using command(s) (same function as "2-D Math > Convert To > 1-D Math Input"). My main problem is, that using the standard procedures in the context menu I get the result of an expression, not the expression itself.

Can you give me an idea, how to do this? Thanks, Csaba

@Carl Love Dear Sir i am trying to solve the system of nonlinear ODE equation with semiinfinite domain by using shooting method . but i am receiving following error 

"Error, (in isolate) cannot isolate for a function when it appears with different arguments"

how can i remove this error. i am unable to find the mistake. kindly help me 

Hi, I build my simulation system in MapleSim, using the module 'Stepper Permanent Magnet' like this

But when I run this system, I get the followiing error:

System is underdetermined

When I delete the part about 'Stepper Permanent Magnet', the system runs well.

How to solve this problem? How to use 'Stepper Permanent Magnet'?

The Help file of MapleSim cannot proviod such help information.

Thank you.

Dear all;

Thank you very much for helping me to understand this problem.

I need your help for this question, it's seem for correct but when I run the code there is no dispaly of the solution with this command  dsolve({ode,ics}) ;

ode:=x*diff(y(x),x)+y(x)=x*exp(-x^2);

ics:=y(0)=1;

dsolve(ode);

dsolve({ode,ics}) ;

Hello maple users,

I want to compare 5 functions and see which one gives the best result (highest score). Unfortunatelly, I can't say one function always gives higher results than others. I have 8 variables and it makes the comparison complicated.

I assume 4 of them are constant and the other 4 or not.

c=0.1

p=1

w=0.5

wu=0.8

for Pb= 0:0.025:0.20                   Pb and Pa are probabilities, between 0-20, 0.025 increments
    for Pa= 0:0.025:(Pb-0.025)      ** Pa is always less than Pb
        for Ha= 0:50                      Ha takes values between 0-50
            for Hb= 0:(Ha-1)            ** Hb is always less than Ha

I attached the data file. I appreciate if someone tells me how to compare these functions. Should I put more assumptions to make it easier? Thank you.
