I have this code (see below) which calculates the probability of finding 4 aces in a 52 card deck through simulation.

My problem is however that the code is very slow and the probability is very low which means that I have to run the

simulation maybe one milion times to get an good approximation. The code can not handle this.

Is there any way to make the code faster so it can handle one million simulations ?

I mean the one that is like in the C language.

It always executes at least once, then more times if the condition holds.

In C it looks like:

do {
 // foo
} while (expression);

This is different to the regular while loop, which only executes if the condition holds initially.

while (expression) {
// foo
}

If I have something like x=5 and I want to get the '5' by itself, how can I do that?

Is there a way to save data that's stored in an Array and put it in a new worksheet?
This is related to my other thread gc() http://www.mapleprimes.com/forum/gc0.

I've used up all my memory as I've had to increase n to a few hundred and the loop is a few million now not a few hundred thousand. So, say A is an Array with 10 million entries (so I cant just copy and paste it), and I want to compare it to another Array with 10 million entries but I dont have enough memory left to recompute the loop.

Hello all,

I'm relatively new to Maple, and I have already found this forum to be helpful. I hope I might be able to get some additional help with the latest problem that I've been working on.

Big picture:

I'm trying to extract two parameter values of a heat transfer problem from a dataset using a reduced order model.

How I've been trying to do it:

The dataset is a vector called "Nodes"

When i cut and paste any maple function from maple input prompt like

> plot3d(x^2+y^2,x=-5..5,y=-5..5);

it takes a long time to paste. I'm using maple 12 and updated to

12.02 but the problem still persists. Using java version 6.0_12.

OS is Debian Etch Linux. Is there any option that needs to be set

that will fix this problem? What can cause delay for this simple

paste?

I was wondering why the permute function in Maple removes [1,1]  [2,2]  [3,3]  [4,4]  [5,5]  [6,6]

for example:

Is there any function that easily gives us the max value of a matrix?

Is Maple able to solve a 2nd order Hyperbolic PDE numerically, with some complex initial/boundary conditions?  what about Mathemaica?

I appreciate any help.

Dear Forum,

this is Vista related.

Maple creates a Maple folder(containing the Maple.ini file) in c:/Users/<username>/Application Data.

Ist it possible to tell Maple to create for this folder in a different place, say c:/Users/<username>/AppData ?

Thanks

Is it possible to compute possible addition chains for an integer in maple ??

If not, is there ANY software that will do it ??

It looks like, choosing a public key exponent with a smaller addition chain makes  RSA decryption more efficient .. but how to know whether or not your exponent has a small addition chain!

Hi all

i've been trying to solve 2 equation with two variables. I got 3 solutions which are complex, i.e. a list  A:=[[ x = ... , y = ...], [...], [...]].

now, A[1,1] gives me the x of the first solution, and I want the real part of it. But when I write Re(A[1,1]) it gives as an answer R(x) = R(...). the problem is that afterwards I need to use this number (for emaple, in pointplot() ), and Maple doesn't let me.

How do I extract the number itself from Re(A[1,1])  (and not a string)?

thanks in advance
