Hello!

I have a problem that has to do with the function dsolve in Maple 14.

This is my code:

Hi all!

I got a task on multidimensional optimization. I need a full code in a maple of this method or method Rosenbrock. I first time see Maple and i have no time for learn syntax of this. (i know only delphi)

If anybody have this codes I would appreciate.

Good afternoon

I have just installed Maple on Linux - Ubuntu, but i have problems.

Please help me. how can i do



I understand this: 23 mod 4

 - it gives me the remainder on dividing 23 by 4

But how can I do the same thing with, say, 23.4 and 5.2?

The reason I ask is because I want to divide angles (float values) by (2*Pi) (another float) and just get the remainder, i.e. I want to discard multiples of (2*Pi) from my angle.

Hi,

Im using odeplot to plot the solution of a system of ordinary differential equations. I would like to extract the data to save them in a file. Ususally I use

a:=plot(...);

points := op([1, 1], a); writedata("file.dat", points, float)

But when a=:odeplot(); this is not working.
Can please somebody help me?

Thanks,

Javier.

I'm trying to use the convexhull function to plot convex hull of points. Explanation of the functions is here

http://www.maplesoft.com/support/help/Maple/view.aspx?path=simplex/convexhull

The problem is that the convex hull of the plot is always shown in yellow background. Is there a way to change the color?

Thanks.

I have a pbs: Suppose 3 vector A, B,C with noted [A:B]:=(list)[ A,B,-A,-B] (i.e a paralelogram);

An endomorphism T such that T(.) where (.)=A,B or C are B,C, and (list)[C,-A,-B,-B]
 and T([x:y])=[T([x]):T([y])] where x,y = A,B or C.

Problem: draw T^{n}[A:B] , i.e its boundary is a fractal figure when n is big.

Hello there,

Im running a fairly big algorithmn with a lot of loops , the memory counter is showing 237.89M and its been running for a long time.

The memory usage has been constant for the last 40min, the time counter still going, and the status bar says 'evaluating'

Is the maple still running fine or has maple's or my computer's limit been reached?

task manager is showing a memory usage of 40% and CPU 12%

I want to use leibniz rule to differentiate the following Integral with variable domain:
A :=(t,x) -> int(Yt^2, x = 0 .. zeta);
Yt and zeta are defined as:
alias(zeta=zeta(t));
Yt:=(t,x)->diff(y(t,x),t);
When I want maple to derive D[1](A(t,x)), its answer is:
2*D[1](Yt)*Yt*Zeta+Yt^2*D[1](Zeta)
Although it uses Leibniz rule correctly, it dose not take Yt as a function of x by mistake. 2*D[1](Yt)*Yt*Zeta should had been derived as int(2*D[1](Yt)*Yt,x=0..zeta).

Hello:

I'm studying many time ago the quantum chemistry of rectivity . so far, I can arrive to news theories from my experince on Maple productcs as they are incorporated in my theoric equations. I have glad  on communicat my previous results on Chemical Reactivity and Uniffied Field. botn of those ara closely related and my purpose is obtain diffusion and comments on these.

- My first paper was on Chemical Reactivity (Kinetics and Dynamics) and...

How can we draw a sequence of segments with a list data of column vector? Thanks

In Arfken(Mathematical methods for physicists,5-th edition,page 483),the asymptotic form of the Hankel function is approximated as

H1(t,s)=

Is there any simple/direct way in Maple(using HankelH1(),or otherwise) to achieve this?I don't want to assign numerical values to t or s.

I'm using Maple 15.  It seems to me this worked in some previous version...

Consider the Lambert W function, y=LambertW(0,x) ... I want Maple to tell me the asymptotics for it,

something like this:

But I don't get that now.  Is my memory faulty that I got it in the past?

Maple 15:

  asympt(LambertW(0,x),x);

not very useful...

series(LambertW(0,x),x=infinity);

with(MultiSeries):
series(LambertW(0,x),x=infinity);

Hi everyone,

I am facing a very complicated system of nonlinear equation. This cannot be solve by using normal fsolve in Maple. Anyone can help me?

Thanks a lot
