hi...
can anyone help me to give an example of loop's command for programming the random data generator?
i have to built programmning for random data that will appear after i've run the experiment,but i have no idea to do that..
please..i've run out the time..

This is probably very elementary, but I am a new Maple user (first day) and would appreciate any help. I am using Maple 11.
I am trying to solve Laplace's equation in a circle and so have set up the pde in polar coordinates.
pde := Diff(u(r, theta), r, r)+(Diff(u(r, theta), r))/r+(Diff(u(r, theta), theta, theta))/r^2 = 0
My problem is that I want to specify initial conditions over a range.
i.e.
u(r,theta)=1 for r=0.5 to 1 for theta=0 and theta=2*pi, and
u(r,theta)=-1 for r=0.5 to 1 for theta=pi.
My problem is that I don't know how to specify the condition for a limited part of the r range.

Hello,
I want to apply the operator (x*d/dx+y*d/dy)^n to a function f(x,y) where n is a natural number.
Is there any way to do it? I could build a loop to construct the final result for a given n but I am looking for something more elegant..

I have a problem with maple11 running on my laptop:Maple Faq tells me :You should configure your firewall to grant full permissions to the following Maple files:
..\Maple 10\jre\bin\maple.exe
..\Maple 10\bin.win\mserver.exe
..\Maple 10\bin.win\cwmaple.exe
..\Maple 10\bin.win\cmaple.exe
But I don't know how to do that:I have Netgear DG834g router,I follow the instructions there to go to Firewall rules, I click on add service and i am lost(nb I am awful with computers).Then I go to services>add custom service and again I don't know what to do...Basically what am i supposed to do??Is a ser

I'm trying to write a loop which will display matrices of larger than 10x10, as an umbrella matrix with blocks of up to 10x10... for example an 11x14 matrix would display as a 4x4 matrix with the [1,1] element a 10x10 matrix, [1,2] a 1x10, [2,1] a 4x10 and [2,2] a 4x1. Any suggestions on how to do this or where I'd find example code?
I'm an undergrad student with only an intermediate level of maple experience so I'll probably struggle with explanations with lots of jargon!

Hi
If anyone has the Global Optimization Toolbox loaded, could you crunch the following worksheet to see if a global minima can be found

I am a new Maple user and I would like a good reference book for Maple 11, specifically one that is geared towards first-timers like myself. All of the Maple books I have seen are quite outdated and they would certainly not discuss the many new features of Maple 11. Thanks!

I'm trying to resolve a PDE system but appear some error.
I use the command pdsolve(sys) an apear the follow error :
'Error, (in pdsolve/sys/info) required an indication of the dependent variables in the given system'

Hello. Does anyone know if Maple has a function similar to NORMSDIST in Excel? Thanks.

Recently I tried to verify or expand on a recent biological statement that I read.
It had to deal with 50 billion neurons each having about 10 thousand different connections each.
After trying to discover the number of operands in the combination of 50 billion things chosen 10 thousand at a time, using the choose command, maple basically crashed.
Approximately, what are the computational limits of maple in general, and combinat commands in particular ?
For example, what is the biggest integer one can take the factorial of ?

Hey,
I'm new to Maple (using both Maple 10 and 11), using it in my Calculus 2 class. I wanted to know if there is a way to find the limit of an infinite series, such as:
sum((Pi+3*cos(x))/x, x = 1 .. infinity)
If I can do it with Maple it will save me hours of work.
Thanks,
Evan

Hi, I just installed Maple 10, and the standard worksheet works fine, but the classic worksheet crashes every time I try to run anything, open anything, save anything, or pretty much do anything at all. What's wrong? I tried turning off my firewall and reinstalling and I'm still having problems. Thanks for your advice!

hi..
i want to ask about command for random generator.can you give examples of cammand to build programmning of generating new random generator.i deal with 10^12 of random variables. i don't have any idea to create the command for this random generator.can you help me?please..

Hello,
Given a system of differential equations as:
C*V = O; where O is a null matrix and C is a 3X3 matrix as follows:
Row 1: [rho*(alpha*I+omega*U*I), rho*U', alpha*I]
Row 2: [0, rho*(alpha*I+omega*U*I), d/dy]
Row 3: [alpha*I, d/dy, M^2*(alpha*I+omega*U*I)]
The prime in Row 1 denotes differentiation with respect to y, and I is the unit imaginary number, d/dy is a differential operator. The vector V is given by:
V = [u; v; w];
How do I use Maple to do a Gauss Elimination on the coefficient matrix which will give me separate equations for each of u, v and w. Or to be more specific, how do I represent the differential operator d/dy in a matrix

Has anyone tried installing Maple within WinXP installed as on OS in Microsoft's Virtual PC 2007 running in Vista? It seems like it should run just the same as it would in normal WinXP. I've run Win98 in the Virtual PC 2005 running on WinXP Professional with no problems.
This would allow Maple to run on the same system as Vista, even though it wouldn't make use of anything relating to additional RAM, additional CPU's, or whatever. Flipping between the two is very easy and it's even possible to share files between the native OS and virtual - at least with Virtual PC 2005 in case one wanted to do something with Maple output files within a program running on Vista.
