Hello everyone

I have a cost function I would like to minimize. It is a fairly simple function that only contains multiplications and additions.

Only problem is, this function has about a hundred variables, but they can only be between the interval [0,1] so I guess it makes the problem easier.

Is it possible to write a little program in maple that can be ran as much as I want it to run and that could try to find an approximation of the actual solution? (By trying random numbers between 0 and 1)

Thank you very much

Can Maple embed ActiveX objects ?

such as discussed here www.quaccess.com/index.html

Hello, I've already posted a similar Problem, but didn't get any answers. Now I think I got the solution, but now there pops up another problem.

I try to run the openMaple sample java code from the samples folder in Maple. I'm running Windows 7 with Maple 13.

When I run test.java, a Popup appears with:

"Error launching OpenMaple splash screen"

with an OK button.

After this, a Popup appears with

"Fatal Error, unable to open C:\Program Files\ Maple 13\bin.win\libgmp-3.dll. This library is required for Maple to run."

Hi,

i got some problems trying to run the example test.java. I have Maple 13 on a ubuntu machine.

for your info:

$MAPLE=/home/thomas/maple13
$LD_LIBRARY_PATH=/home/thomas/maple13/bin.IBM_INTEL_LINUX


Now the problem:

Compiling the java file works, but when I try

java -classpath "$MAPLE/java/externalcall.jar:$MAPLE/java/jopenmaple.jar:." test

this exception appears:

Error loading libraries: java.lang.UnsatisfiedLinkError: no jopenmaple in java.library.path
 

My goal: given G(z,w), find the polynomial, P(n), in the partial derivatives of G(z,w) over the integer such that 

d^n z/ dw^n = P(n) / Gz^(2n-1)    where Gz= partial derivative of G with respect to z.

Step 1. Differentiate G(z(w),w) w.r.t w n times. Formulae are known for doing that (Mishkov, Tsoy-Wo Ma),

Dear Maple Users

I am trying to minimize a cost function C subject to conditions t1>0 , t2>0 and t1< t2 by using maple 10

It seems a picture inserted or plot command generated is not movable in a document ?

If I shrink the picture,that will be in the center of the page,but this is not good when I should print the document.

can't be dragged to anywhere?

What keyboard configuration must have the Win XP to use the keyboard shortcut "Shortcut Keys" and not the key combination "International" to introduce 2-D math expressions. I refer to the help "2-D Math Shortcut Keys and Hints".
The configuration I have enabled is:
Input Device Language: Spanish.
Keyboard layout / IME: United States International.

Does there exist a simple trick to permanently save imported csv data inside the Maple worksheet.

Everytime I reopen the worksheet I have to import the data again. I want the data to permanently be there.

I tried to specify interface(rtablesize=1000) and the import the data, and copy the data and past it into a code edit region

however my data has 500 columns so it is close to impossible to copy it inside maple it takes 10 min just to copy it

my system [u(t),v(t),w(t)] is highly non-linear. I want to understand the local behavior at [u=0,v=0,w=0]. The boundary conditions are as follows: u(0) is given but v(0) and w(0) are not. I want to know if there is a suitable choice of v(0) and w(0) such that the system will converge to the critical point [0,0,0].

Can this system be approximated by a linear system? Or by a two-dimensional system?

Hi,

How can I plot two boxes with gnuplot in 3 Dimensions, one small box inside one big box? 
I know that it is possible with 
plot3d(Polygon([[x11, y11], ...[xln, yln]], [[x21, y21], ...[x2n, y2n]], ...[[xm1, ym1], ...[xmn, ymn]])

but how can I do with mathematical equations?
 

I have a 3-dimensional dynamic system of ODEs characterized by zero eigenvalues at the origin. I would like to know if it's possible to find one trajectory converging towards the origin.

My system is derived from a control problem and has consequently control-like and state-like variables -- while the neighborhood is typically unstable I need to know if an appropriate choice of initial values can steer the system towards the origin;  I expect at most one such trajectory.
