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...

Here's a Maple trivia question: There is a Maple symbol that cannot be used as a procedure parameter. As far as I can tell it is the only one. What is it?

I am currently running sucessfully Maple 15 on Macbookpro mid 2009 4G, CPU 2,53 Ghz Intel core duo, NVIDIA GeForce 9400M 256 Mo, OSX 10.8.4

I bought the upgrade to Maple 17, when launching the install package : I have a grey window with a "next" button with slow flashing : impossible to click on it ... so impossible to install the new version

thanks for your help !!

by the way Java installed

best regards

Gaetan

Hi,

     Seems like a silly questionm but the Maple help page suggested usign the option 'interpolation=false' for a numeric dsolve since I ran out of memory (I'm solving a huge matrix DE). But that's not an option in the command dsolve, has this been removed as of Maple 16? Or any suggestions on using less memory? I have 16Gb RAM, 

Thanks

Thirteen Clickable Calculus examples have been added to the Teaching Concepts with Maple section of the Maplesoft web site. The additions include examples in algebra, differential and integral calculus, lines-and-planes in multivariate calculus, and linear algebra. By my count, this means some 97 Clickable Calculus examples are now available.

In the Algebra/Precalculus section, examples of an

I seem to recall from my undergrad days that a cubic polynomial could be readily factored (even analytically) if you appy the assumption that you will have 1 REAL root & the other 2 are complex conjugate pairs.  I cannot seem to find my old lecture notes & see nothing on the web on this matter.

Anyone here have any knowledge on this subject?  I have played with MATLAB & altered the polynomial coefficients such that whenever complex roots do crop...

Does anyone know why png is not listed in the help on plot/devices?  The png device exists and works.

Also, are there any other unlisted plot devices?

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

Hello, I'm a newbie in Maple. I just started learning maple and i'm using version 17. I want to know if there is a way in maple to get the coefficients of some variables maybe an example would explain me better. Lets say we have

23x^4 + (12*h)x^2

So my question is that is there a function/method that can allow me to strip the coefficients of x^4 and x^2. Because I have a very long expression and I need the coefficients of the variables therein to populate a matrix.

I have reason to believe that the expression below is a real number: 

(1/6)*(-108+(12*I)*sqrt(1419))^(1/3)+10/(-108+(12*I)*sqrt(1419))^(1/3)+1;

A numerical approximation supports that. How can Maple help here to get a simplified expression?

Good day,

I have plotted a family of lines in one graph, and now I want to shade an area between two horizontal (parallel) lines, for example 2 and 5.
So what I did was to use the command 'filled'. First I shaded the area in vertical direction from 0 to 2 white. After that I filled the area in vertical direction from 0 to 5 for example blue.
This results in a shaded area between 2 and 5 in the color blue, what I like to have.

Question: Is there a way (a command) to fill an area between two horizontal lines more easily? So that I shade it between 2 and 5 in just one commandline. Now I first make a part white, and then the next 'layer' behind is in the color I'd like to have.

Another thing is that when I shade an area in the color white, my gridlines disappear! Is there a way to avoid this?

I have found information about shading area between two intersecting lines (can be done relatively easy), but between two horizontal (parallel) lines I still can't find a simpler way to do it.

Somebody got a suggestion?

Greetings,
Frank

Hi there,

i would like to know, how can i change the x-axis labels of an graph?

Currently i read data from text file in format like this:

0 10

1 11

2 14

3 15

This values i plot in a graph with this commands:

averagedValues := readdata("mytextfile.txt", [integer, float]);
plot({averagedValues}, x = 0 .. averagedRowCount)

My problem is, that each x value has a date label....

Dear Maple Developers,

Maple offers OpenMaple, which is nice and sufficient for driving Maple from extermal applications.

On the other hand Maple offers only very limited support for calling Java methods from maple (static emthods only, no objects).

So it is only possible with programming some extra static Java adapter classes to work with Java objects and their methods. This is a very cimbersome and clumsy workaround only.

Compared to applications...

Hello,

I think the answer to my question is not there yet.

So I would like to save some variables in a .m file in an another folder without using the whole C:/.../ thing.

The reason why is that I am using a windows and a mac so if work on my mac I can still execute my reading and my writting commands on my mac.

the file I want to write from is located in :

/Maple_projet/Code/Timoshenko/

and the folder I want to write to is in
