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

Hello, I'm a recent arrival at Maple Primes (as in earlier today), and I seem to recall a much older version of either Maple, Matlab, or Mathematica having a 3D plot example of a "Schauberger" tube. I've looked through my old files and can find nothing. These are similar to a tornado or water whirlpool profile, so I'm supposing that cylindrical coordinates are a suggested goemetry. A "decaying radius" spiral looped inside the "Gabriel's Horn" elsewhere on Maple Primes has a similar 3D profile, but the pipes that Herr Schauberger patented in Austria long ago also decreased in pipe diameter as the spiral radius decreased inward.

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, is there any other possibility to export Maple 3D graphic into VRML scene with axes and labels? When I use the plot3d(3*sin(x)*cos(y), x=-Pi..Pi, y=-Pi..Pi, style=patchnogrid,axes =framed, tickmarks=[3,3,3],grid=[50,50]); o:=%: vrml(o,`krychle.wrl`,tickback_color=brown,tickfore_color=yellow); i receive the VRML file with axes tickmarks as cubes. For an example of 3D graphics in VRML format with axes and labels see Holodraw. With best regards Roman

Hi If anyone has the Global Optimization Toolbox loaded, could you crunch the following worksheet to see if a global minima can be found rgds View 2735_NLPSolveT8-global.mw on MapleNet or Download 2735_NLPSolveT8-global.mw

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 ? v/r,

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!

/ ranting on I use Win XP home on an Acer, which has an Athlon (do not care for specifica). It installs with a blank space in the directory name as default (which may cause troubles if using Open Maple with MS compilers). Installing Watcom not even gives a warning to prior installed ones (so I hope it does not matter ... say having some modifications in it [well, a backup is never a bad idea before any install ...]). It does not adapt settings from M10 (I think 9.5 -> 10 did so), i.e. global settings and style sheet had to be done again. And: it does not associate M11 to *.mws (classical sheets are my default).
