I have tried to do it by the following command "File/Modelica/Import Modelica Library" in MapleSim GUI. An error appears saying "Modelica is a reserved name".

I think you can also reproduce it by downloading the Modelica library from the following web site: "". And then importing it in the usual way by openning the file at the root directory.

I think I am missing something here, so any advise/information/minimal commentary would be greatly appreciated.

#Hello people in Mapleprimes,




#shows f'(x).



#shows just df(t1)/dt1, not f'(t).

#Can't I show f'(t1) not df(t1)/dt1?

#Is this a way peculiar to Maple?

#I hope someone could give me some hints.


#Best wishes.






i work on Maple 18 and recently maple standard worksheet interface not run properly.

i already have  uninstall and again i have same problems

(1) I keep trying to enter a reply, and it just never appears. What's wrong?

(2) How do I get code from the Standard GUI to paste into a reply?



Do anyone know the keyboard shortcut to the standard subsribt in Maple 18 on a macbook with OS X? 




How can I get the Standard Errors of the covariance matrix in Maple?
I can simulate a covariance matrix in Maple as follows:


R := RandomMatrix(4, 4, generator = -15 .. 15, outputoptions = [datatype = float[8]]);

but how do I find the standard errors?

Maple 16 is crashing when saving. I have this problem in both

my desktop and laptop (PC, Win7), classic and standard worksheets.

I noticed that short files present no problem, but whenever the

worsheets are, say, more than 5 screens length, Maple 16

crashes when saving.


Anyone with the same problem? Any solutions? Thanks




How do you export an array of plots from Standard GUI? If I select the array with the mouse and then right-click (to get the context menu), my selection is reduced to the single cell of the array that the mouse pointer is over. Do I have to resort to plotsetup?

In the 20-29 age group , the heigts were normally ditributed with a mean 0f 64.3 inches and a standard deviation of 2.6 inches

find probability that her height is less than 56.5 inches.

A user recently sent to me a Maplet that includes the display of an array of plots. This maplet works fine when run under the classic interface but not under the standard interface. As I tried to understand this problem I believe I have narrowed it down to a difference in the way the classic and standard interfaces handle an array of plots.

The attached worksheet is a very simplified example that shows the problem. What should happen is that pressing the "Plot single" button should show a single graph, pressing the "Plot array" button plots the empty axes, and pressing the "Plot displayed array" button displays a 2x2 array of plots. The second and third buttons illustrate the need for "plots:-display" in the action definition for this button.

Unfortunately, this works only in the classic interface. In the standard interface the "plot displayed array" button does not display anything. I should add that it appears to work correctly when exported as a .maplet file and run with the Maplet Viewer.

I have uploaded the worksheet:

Maple 15, Windows7x64, Standard v. Classic

I have noticed that, on my system, the smoothness of some INLINE plots is better in Classic than in Standard. Is this some regression or some installation-specific quirck I wonder?

In Tools->Options, I have plot anti-aliasing enabled (whatever that is).

This looks alright in Classic

  [ x^2 + y^2 = 1, x^2 + y^2 = 2 ]
  , x = -2 .. 2
  , y = -2 .. 2


I have a problem that Maple 15 is not possible to start (process is there but GUI is not visible).

On the same computer (HP 8540w) I have the problem with Maple 14 too. The GUI is started but it is not possible to do any action in it because it does not respond.

This problem occures now. I am sure that some months ago it works properly.

If you have any suggestion I do welcome it.



How would you transform a 3D plot structure into a 2D plot structure? I have in mind 1) creating a 3D plot with odeplot or with plot3d, 2) selecting (say) 4 orientations, 3) transforming each into a 2D plot, 4) exporting the 2D plots using the Standard GUI.

The reason behind my question is that the best-looking exported plots that I have been able to obtain with Maple are 2D plots exported as postscript with the Standard GUI. 3D plots don't look nearly as good when...

I should convert factors of a generic equation into standard form (scientific notation) :


 example_eq := 345.1234 x1(t) + 34.5691 u1(t) - 5423.8932 y1(t) + ... many other terms...

Is there some maple command or procedure to convert automatically every factor of a generic (very long)   equation ?


Manipulating a system of long equations maple gave in output the following error message:
