Hi,

I need to model the MapleSim ground as a hard ground. For example when the robot swing leg hits the ground, it should not have negative vertical position. Basically, the robot will move on a surface.

Thanks...

Hello every one,

While plotting contours with grid size [200,200] my computer consume too much time to

execute the commond. To have an idea, the current process which I am running right now already

took 2380.22s and 68.60M and still its on.

Any suggestion to make the contour plot process faster?

Thanks

Hello,

This is more of a tutorial rather than a question because I found some mistakes and because the maple help file was a bit poorly explained and I am posting some additional details.

I am running version 16 of maple and version 7.12 R2011a of matlab.

If some of you are wondering how to call a Matlab user function in Maple this is what I have done:

First of all in the maple...

When I export my plot to PDF, adobe acrobat says: A drawing error occurred. Other programs see my PDF as corrupt. I would use a .eps file, but my plot has a semi-transparent component that doesnt show up very well as an eps. Any ideas?

Thanks

I recently purchased a new MacBook Pro (retina) with Mountain Lion and found that my Maple 12 programs would not run.  So I updated to Maple 16.  Initially all seemed to work well.  But now when i try to open a Maple .mw file, I get the message

"File acm23test.mw could not be found.  Please select a different file."

What has happened and how can I get my programs working again?

M = (1+y^2)/((x^2+1)*(1+z^2))

Anyone have any background knowledge on the above 3D polynomial?  Assuming all 4 parameters are real I ploteed some 3D plots & some interesting surfaces are generated.  I imagine this has some physical application.  If anyone has some knowledge on this please respond & include any references you might know of.

Thanks

Hi everybody,

I already discussed my tasks with @Preben Alsholm. Therefore, I decided to share it with you and try to finalize solution.

Actually, I want to calculate heat dynamics transfer between one, two or more rooms. Hence, I used heat balance approach to set the system of differential equations:

In the following code, why is B returned unevaluated?

restart:
A:= a:  B:= 2:
F:= _a-> eval(`if`(A,B,C), a= _a):
F(true);
                               B
eval(B);
                   ...

The "ExcelTools" seems can work based on Excel 2003 format,which can only support 2^16 rows.Excel 2010 format cantains much more rows and columns. So I want to know when maple can support Excel 2010?

Yesterday I’ve updated to the new Version 17.01 and now I’ve the problem that I cannot enter  ‚}‘ and another problem is an exponent e. g. x^2. To enter it I have to write x^22. The first number is not shown in the worksheet.

I hope someone can help me to solve this problem.

Are you in or near Berkeley, California?

Are you experienced with Maplesoft for academics?

Can you train a student to use it with the tutorials and your own knowledge?

This student is located at University of California, Berkeley and needs an immediate hands on private trainer.

He will be taking Calculus 1A next semester and needs to learn to use this program this summer.

He is a student who uses an eye control computer without the use of his hands and needs this

Hi, 

     I'm computing some difficult integrals, involving Spherical Harmonics. I've proved that the answer must be a real number, and yet Maple returns a complex number. Also Mathematica returns purely real numbers, so I wonder if there is a bug in Maple. I found if I break the integrand into real and imaginary parts, and add them I get the right answer...usually.  Anyway's here's the code and the proof, I suspect they could be a bug...

hello, i'm using maple, in order to draw a graphic in wich, different functions are plotted, 
these functions came from one with 4 variables, wich represents losses in a phenomenon (extraction) depending on diffenrent variables, so my objective is to varry only one parameter and then draw its curve, and this for each parameter ; i had 4 functions.

with(plots):

f1:=plot((n-1)/(-1+n*10^(6.77*((n-1)/n))), n=1.0537..1.2688):

f2:=plot(0.2365/(-1+1.2365*10^(0.0155*O)), O=76.42..99.92):...
