I have maple 13 for Mac OS X version 10.6.2. Initially maple worked fine but suddenly it didn't seem to recognise keyboard shortcuts. Then when saving a worksheet all it did was save a blank one. Later it threw out a couple of two dimensional blue lines when using PDEplot. And recently it won't export any plots. In short maple is even wore than windows (and thats saying something).

Dear Friends,

I have Maple v9.5 on my laptop. I would like to know how to take the inverse cosine and sine transform of a function.

Since I am using Integral Transformation to solve PDEs, it is of great importance to me.

Best,

Maziar

How can I round off the numbers in a random array or matrix?  Round or Trunc will not work on a random number.

with(ArrayTools):
a:=30*(ArrayTools:-RandomArray(8,8));

 

I replied to the following thread but after further thought I probably start a new thread:

hey all

I want to write an algorithm similar to this but instead of ''w1:=a+h''   I have to put about 75 commands. how can i do this?

 

Can someone help me please?

 

Hello all!

I am an Open University student just starting with Maple 11. I am studying the course MS325 Computer Algebra, Chaos and Simulations and we have to use the classic interface.

I use Fedora 11 Linux on my Acer Aspire One netbook. I have loaded Maple 11 for Linux, and the standard version opens OK by using ./xmaple

But if I try to open the classic interface with ./maple -cw

I get this:

I know it is possible to change the "Look and Feel" of Java applications, and i was wondering if there was any way to do this on Maple? (Maple 13 for Linux, to be exact.) 

What am i doing wrong?

Error, (in int) invalid arguments

 

Can i make an algorithm like this in maple?

w= 4

for k= 1 to 10 do

             for h = 1 to 20 do

                      for a = 4 to 15 do

                               w1= a+hk

Objective: plot a graph from data drawn from two arrays. I would like to have the data points marked with a symbol (point, circle, or diamond, etc.) on the graph. How do I do that? Following is the code: -- two arrays of data point: engineeringStress and epsilon(engineering strain) -- Zip is used to put two arrays into data points (x,y) to create stressStrainData -- plot is used to graph The plot shows a line; I would like to have the data points marked (visibly seen) on the graph. Thanks. --mdc > restart; > with(plots); with(plottools);

Hallo,

I would like to create a literal subscript using a mac and international keyboard.

Unfortunately the symbol on the expression palette does not work so I need to use a keyboard shortcut. I have been searching the internet and maple help for hours, but I cannot find it. What I did find is:

Hi all,

Is there a way to call Eigenvectors(), order the returned eigenvalues from largest to smallest, and have the returned eigenvectors reflect this ordering? I've tried a sort() on the eigenvalues which orders them successfully, but I can't seem to figure out how to apply the ordering changes to my eigenvectors.

Hi all,

I am trying to substitute 2 solutions from each loop into a general matrix but i cannot do this.
