Let say that you have two matricies:

X := Matrix(Statistics[Shuffle]([seq(x[i], i = 1 .. 100)]));
Y := Matrix(Statistics[Shuffle]([seq(y[i], i = 1 .. 100)]));

For example the matrix x could be:    x[45]    x[12]     x[2]     x[10]      etc
For example the matrix y could be:    x[12]    x[1]       x[20...

(1) Does ModuleCopy, when automatically called from Object,  really get the a shallow copy of the object

as the first parameter in its parameter list? See below, which is copied directly from ?object,create. The

ModuleCopy has first argument new::Dollar but ModuleApply only passes its two arguments not three. I

couldn't find a reference to this feature in the docs.

hi

i have the following ode

.7246228659*(diff(f(x), x, x, x))+f(x)*(diff(f(x), x, x))+.6666666666-.6666666666*(diff(f(x), x))^2

with boundary conditions

f(0) = 0, D(f)(0) = a, (D(f))(b) = 1   (b corresponds to infinity and we can assume it 4 or 10 such that the solution converge)

i know the the solutions exist up to a critical value of "a" that beyonds no solution exist. for example for the following ode the critical value is...

I'm using the 64-bit version of Maple 16.0 and Excel 2010 (32-bit). (Most people using Office 2010 install the 32-bit version on 64-bit operating systems.)

Is it possible to use the Maple addin with the above setup ? I tried selecting WMIMPLEX64.xla, but Excel appears to want WMIMPLEX.xla (from the 32-bit).

What is the easiest fix ? Can I find a copy of WMIMPLEX.xla and use with with Maple64bit and Excel32bit ? Do I need to uninstall Maple64-bit and install Maple32-bit ?

Please name the post, which had the most visitors.

Many Thanks!

For L a given L-function (such as the Ramanujan-tau Dirichlet series) I would like to compute L(s) at 2.5*10^5 values of s equidistributed in a square region of the complex plane in a reasonably short time (meaning, say, less than an hour.) Is there a Maple function that will do this, either in the original software or available on the web?

The basic plot routine in Maple 16 has a serious problem with the domain.  The following is an example.

The domain is correct in Maple 15.  This failure occurs in both Windows 7 and Linux.

I have been generating graphics in Maple 16 using the plotsetup(ps,...) command under Windows 7 and Linux.  Maple tech support has a fix for Linux and has confirmed that there is a bug in the Windows version.  These are a Windows eps (converted to png for uploading) and png of the same figure.  The eps conversion should not do this.

Hi, i'm interested about parallel programming in maple but i cant find a good tutorial. is there anyone know a good refrence for this topic?

Hi,

I want to parallel the following code.it is good that part1 solved by one thread and part2 solved by other thread.

please help me.it must be noted that part1 and part 2 are independent "at each" iteration.

 

dtheta[m](x):= theta[m-1](x)+phi[m-1](x);
dphi[m](x):= theta[m-1](x)-2*phi[m-1](x);

for i from 2 by 1 to 10 do;

# part1

theta[i](x):=subs(m=i,dtheta[m](x)):
theta[i](x):=value(%):
eval(-theta[i](x),x=0);

There is a utilde on the Latin pallette, among others. How do I get xtilde as a variable?

I want to create a simple executable bat fil.

1) When I click on it maple should launch in the background (I dont want to see maple open)
2) Then Maple should open a txt file located on the desktop (containing a 1), read the file
and save  a new txt file on the desktop containing the number in the previous fil +1.

How can this be done?

i study a simple differential equations as follow and get the solution,but i faced two warning which puzzle me:

> restart;
> eq2 := diff(x(t), t) = x(t), diff(y(t), t) = x(t)^2+y(t)^2-1;
   ans1 := dsolve({eq2, x(0) = 1, y(0) = -1}, numeric, [x(t), y(t)], range = -10 .. 10)       ;

Warning, cannot evaluate the solution further left of -1.1646698, probably a singularity
