I've posted  a code for a procedure, but it seems it does not execute with other versions of Maple the way it does with my version (5.4). Here is the link. I am curious to identify within the procedure code the cause of this divergence. Note: in 5.4 the code is preceded with readlib(eliminate).
 

When transfering a particular worksheet from my home Windows 7 computer to an office Linux computer I lose some of the end of the worksheet, namely I lose a rather memory intensive animation at the end. And the office compute crashes when I attempt to run the animation. This seems strange since apparently the office computer (see below) is more powerful than my home computer.  When this happens there are apparently few if any other users of the office computer. I  would be grateful for suggestions for remedies for this problem or any ideas of what the problem could be.

Hello, 

I loaded Maple to my friend's PC. But we can not execute any command in worksheet. When we write some lines and hit enter, it does not respond in anyway. (excluding simple calculations such as: 2+3 etc.) What is the problem and how can we solve it? 

PC: Windows 10

Hi everybody,
 

I write a worksheet which contains thesimple code provided in ?Maplets[Button] :

with(Maplets[Elements]):
maplet := Maplet(["Select one:", ......]) 
Maplets[Display](maplet):

As mentioned in ?MapleViewer it is possible to export a worksheet in a .maplet file (I use Windows 7) and to execute it by double clicking on the corresponding icon.
I proceeded as explained in the help page
But double clicking does not work with me : a "User Interface Customization System" window opens and shuts after a few seconds without displaying the expected maplet 

(right click + open with and select mapleviewer.exe shows that mapleviewer.exe does exist, so the issue does not likely come from an incomplete Maple installation).

I tried a few variants of the worksheet, such that
with(Maplets[Elements]):
Maplets[Display](Maplet(["Select one:", ......])  ):
or even
Maplets[Display](Maplet(["Select one:", ......])  ):

But it keeps getting bad
Could you please help me to fix this ?

TIA

Dear 

Hope you will be fine. My file takes to much time to solve the system of nonlinear algebraic equations for Iterations=8. please solve my problem I will be waiting for positive response.

Hello all, 

A question concerning NetCdf files was asked in 2012 and is still unanswered today.
Browsing the questions only returns this item, suggesting the NetCdf topic is not a concern in the Maple community.
Nevertheless, does it exist some capabilities in reading and writting NetCDF files ?
If not, are there some planned development on the subject ?

Let's hope now for not having to wait four years for an answer, all responses will be greatly appreciated, even negative.

years

PS : NetCdf capabilities already exist in Sage or Mathematica

I'd like ot make a 3d graph that is log scaled on at least one of the axis. So far I haven't found a way of doing this that gives a graph that I genuinely like.

The following worksheet shows two ways of making the graph- the first generates the lines on the surface in a very bunched way, the second typesets the tickmarks in a very ugly way.

How can I get a graph with well placed lines and nicely typeset tickmarks?

How do other people make 3d logplots?

In paper of Nail H. Ibragimov there is operator given at equation 2.10 which he call by name Euler-Lagrange operator. How I can use this operator in Maple to derive adjoint equations ?
I have attached JPEG in which I want to apply this operator to Lagrange identity "I" for adjoint equations.

I have to generate a code for carrying out the matrix form of the revised simplex method. I have a code in place but am struggling to convert the constraints into canonical form and introduce the penalty function. If anyone has any ideas I'd be very grateful!

Best Regards

I just happened to be searching older posts and could not find this one I created

It must have be zapped by a spamming filter or something. 

**edit added**  heres another I can't seem to find

Hello

Hope everything going fine with you. I am facing problem to fine the exact (numerical) solution of the attached system of linear PDEs associated with BSc and ICs. I tried to solve it without BCs and ICs, with BCs and with ICs also all the times I failed. Please solve it either general, with ICs or BCs. You can try to solve it numrically. In attached file H(t) represent the unit step function. I am waiting your positive response.

I tried to solve a symbolic nonlinear system, which is shown as following:

The S,T,B is three parmeters. And I want to express X and Y by S,T,B.

However, when I use eliminate({},{}), an Error comes as following:

Error, (in SolveTools:-Basis) invalid input: ListTools:-Transpose expects its 1st argument, L, to be of type listlist, but received [[1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0], [1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0], [1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0], [1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0], FAIL, FAIL, [0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0], [1, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0]]
 

I have no idea about this problem, who can give a help?

Thanks!

What shall I do to install Maple 15 and MapleSym 5 in a Windos 10 environment.

I find the procedure in Maplesoft site up to Windows 8.

May I follow it for Windows 10.

Thank you for any help. Kind regards

Can i make Explore with number of parameters differs from parameter in explore?
For excemple i whant to make sum with 'l' values wich will declorate in explore, and 'l' - count of them will declorate in same explore, but it dont work, so is it posible?
