I want to generate a set of numbers of fixed size with maple, when I use the rand procedure within a fixed integer range let us say rand(1..2^4) and ask maple to pick 8 integers, maple will pick 8 different integers in the required range.

I would be grateful for any help.

Hi,

I have defined my group in maple as

G:=grelgroup({u,v,w},{[u,v,u,1/w],[v,u,v,1/w],[u,u],[v,v],[w,w]})

I now want to define a function on GxGxG. Previously I have used array, i.e. f:=array(0..2,0..3,0..4), but how do I do it for elements in G?

Many thanks,

Jenny

Hello everybody, I'd like to write from a procedure results in a table as output. Something like this, that I show at the end.

I got my 8 coordonates, I wanna plot a cube. When I all my coords in pointplot3d, it connects p1 to p2 to p3 ..to p8 so it doesn't make a cube. How do I make it so it connects the coords I want to make the cube. Thank you

Hi:

Concerning Maple 12 I note the following behavior:

cos(alpha-beta) displays as typed

cos(beta-alpha) displays as cos(alpha-beta)

Similarly,

sin(beta-alpha) is displayed as -sin(alpha-beta)

Anyone knows the xplanation for that and possibly how to prevent it from happening?

thanks a lot.

In the volume Advanced Programming Guide of the Maple manual, the "clasical" picture of the Maple system architecture is depicted:

 A1: Internal Organization

Components

Maple consists of three main components: a kernel, a library, and a user interface. The kernel and library together are known as the math engine.

Kernel The kernel is written in the C language and is responsible for low-level operations such as arbitrary precision arithmetic, file I/O, execution of the Maple language, and the performance of simple mathematical operations such as differentiation of polynomials.

Library Most of the Maple mathematical functionality is in the Maple library, which is written in the Maple language. The library is stored in an archive, and pieces of it are loaded and interpreted by the kernel on demand.

User Interface The user interface is the part of Maple that the user sees, and is conceptually separate from the math engine. The same math engine can be used with different user interfaces.

However, the architecture of the system has been moving away from this picture for several years already. Eg:

A second parser has been implemented in the Standard GUI, instead of the kernel.

Kernelopts(multithreaded) returns true for both my P4 hyper thread processor (which is fine) and also my P3 tecra 8100 laptop. huh?

Isn't multithread only supposed to return true if there is hyperthread technology on the chip or the processor was dual core or dual processor.  Why is it returning true on my laptop P3 single processor? 

In order to optimize a large number of datasets I integrated the GlobalSolve command from the OptimizationToolbox
in a for loop. The code (in short form) looks like this:

for i from  1 to 100 do
data(i):= "read data from external file":
Z:= "function to optimize based on data(i)":
with(GlobalOptimization):
infolevel(GlobalOptimization):=4
B:=GlobalSolve(Z, a=0..2, b=0..2, c=0..2, timelimit=6000):
->Solution of optimization is exported to external file
end do:

How do I graph multiple functions on the same plot, and possibly with different colors for each line. Thanks in advance.

I have some tough maple questions if you guys think you can handle them, let me know, i could use the help but also if you like a challenge, i think you'll get a kick out of the questions.

write me a message and i will send you a link to the questions (i scanned and uploaded the image of the questions on the paper)  just a few questions but tough ones!!!

Any help would be appreciated!!

thanks guys.

Hi all,

While trying to solve the Legendre ODE, my serie (obtain by Frobenius method) was transform by Maple by the following:

> y1x(p);

                             /[  1    1   1  ]  [1]   2\
                    hypergeom|[- - p, - + - p], [-], x |
                             \[  2    2   2  ]  [2]    /

where y1x is my serie and p is the degree of the ODE.  But at the screen, the output is:

So my questions are

1.  What the 2 and the 1 around the F means?

2.  Is it normal that this special function is the solution of the Legendre ODE?

(in fact, I test it for different p::posint and it worked)

3.  Can someone help me to have the ratio |a(k+1)/a(k)| so I can do the ratio test for the convergence of that serie.  In fact, any additionnals informations ,other than the helps pages, would be very welcome.

Thanks in advance

Is there a way I can plot 5 different functions together?I only require specific sections of the graphs, like between [0,3] for the first, (3,6] for the next, etc?

Thanks!
