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.
Gracias

Hi, I am wandering whether are some functions to compute all irreducible polynomial and prmitive polynomial over Galois field. For example, I want to all the irreducible and prmitive polynomials of GF(2^5). are there such commands to perform that? thanks

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

(-1/x)*ln(1-x)-x+2=0:

please can you tell me how can I solve this equation.

I am trying to approximate the solution of vi_vh to vi_vh = 1 / sqrt(vx_vh^2 + (vi_vh+vz_vh)^2) with the expression vi_vh = a * vz_vh^3 + b * vz_vh^2 + c * vz_vh + d + e * vz_vh * vx_vh^2 where b and d are zero The approximation is for the region -2<><>

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 all, Is there a feature in Maple to collaborate? I mean: is it possible to work at the same maple file from 2 different computers simultaneously and join the results? It would be great if there's the possibility to work in real-time together, but comparing the files after editing and combining the changes to both documents in one Maple file is already satisfying. Thanks in advance for your advice. Giel

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.

Hello,

I'm try to access some external Fortran routines within maple. I have a Fortran datatype of

  character*255 hf(20)

This is an input parameter, and I believe this will map into a maple Array object, but I'm not sure of the datatype. The help says that the datatype can only be "hardware datatypes" so I take to mean it would have to be of type integer[4]...when I do this I get the error below.

Hello all,

Am a very new Maple user (installed today), so please bear with me! I need urgent help with the following:

I am trying to simulate polymerization of PMMA and have the following problem:

(1) I have Temperature-time data, measured experimentally.

(2) I want to fit my model which gives me a relationship between the rate of change of temperature (dT/dt) and the temperature in terms of a number of parameters:

dT/dt = Q*[Z*{exp(-E/R*T)}*{a^m}*{(1-a)^n}*{1-a}]

where,

a = P/Q + a0

Here,
