Subject: export animation ---> beamer / pdf? is in the newer releases "animated gif" still the only option for exporting MAPLE animations? if so, what is the best way of getting this into a beamer (via latex/pdflatex and acroread) presentation -- prefer- rably portable to any machine that has acro-read installed (want to bring the talk on a memory stick, don't bring the laptop -- yet not worry about installed helpers). so far my pdflatex accepts in beamer mp4 movies, and I can convert single frames of gif to pdf, but not animations.

I was wondering if there is a way to animate a plot composed of points from a listlist. The points are x/y cordinates read from a file and then placed into a listlist for plotting. In other words, I'd like to use the animation controls to animate the drawing of the plot shown below. tListList := [[2.3, 1.1], [3.4, 2.3], [4.3, 5.6], [5.3, 6.7], [7.2, 8.9], [12.4, 2.5], [13.4, 12.5]]: with(plots); with(CurveFitting); tSpline := BSplineCurve(tListList, v): plot(tSpline)

I've made some animations in maple that I could like to show in a power point presentation. Does anyone know how this is done most easily?

Dear all, I am trying to write a little program (called "rcltnn") which calculates a recurrence. The problem: Maple does not return numbers but strings which arrise from the recurrence. Example: for n=4 I expect to get rcltnn(n=4)=95, but Maple gives 15+7*rcltnn(2)+6*rcltnn(3) Actually, that string is correct but not fully evaluated. We have rcltnn(2)=2 and rcltnn(3)=11 (further values are rcltnn(1)=1 and rcltnn(0)=0). Here my program (I have played with many versions of this program) rctlnn := proc (n::integer) global j, rctlnn; option remember; if n = 0 then rctlnn := 0 else rctlnn := combinat:-bell(n); for j from 2 to n-1 do rctlnn := rctlnn+combinat:-stirling2(n,j)*rcltnn(j) end do; end if end proc;

kernel shutsdown when memory usage reaches 1.8 GB i tried the following combinations: maple 10.06 on amd 3500 3GB XP maple 11.00 on amd 3500 3GB XP maple 11.00 on dual xeon 4GB XP maple 11.00 on quad xeon 8GB XP 64-bit in version 10.06 maple terminates with memory allocation error in version 11.00 the mserver process terminates without notification the problem consistently occurs at a memory usage of approx. 1.8 GB i am using GRTENSOR however the bug occurs in pure maple computations, specifically with the SIMPLIFY command any idea?

Why Maple 11 does not reply by true for the following snipped:

assume(m::real):
PIECEWISE([exp(m)-exp(-m), m <= 0],[0, 0 < m]) = min(0, exp(m)-exp(-m));
convert(%,piecewise,m);
is(%);

It handles the 3 cases 0<m, m=0, 0<m correctly. I find that strange.

I was trying to do something that I thought would be really simple - without success - then it occurred to me what was missing... a couple of quotes. There's other ways to do the same thing, but this is just the way I was trying to do it. sum all primes up to a certain count. ithprime returns prime up to cnt ( no quotes required ) no quotes required -- sum(ithprime(b), b = 1 .. 5)  #adds 2,3,5,7,11 sum all primes up to a certain number. quotes are required -- tprime := proc (s) if isprime(s) then s else 0 end if end proc sum('tprime(n)', n = 1 .. 12)  #adds 2,3,5,7,11

Hello everybody, I have a question please. I would like to resolve an optimization program. The objective functions are not linear and the constraints are the inequality functions. Can somebody tell me if we can resolve this type of programs with maple. Thanks a lot, Sarah

One issue that often confuses users is local versus global optimization in Maple. I'm just going to give an overview here and will explore specific optimization topics more deeply in future blog entries. Please note that I'm covering only the numeric optimization methods here. I'll leave discussion of the exact methods in Maple to others more knowledgeable about those areas.

The Optimization package is built into Maple and is available to all users. This is primarily...

When working with large sparse linear systems you often want to look at their non-zero structure, however Maple's existing tools are all designed for dense matrices. I wrote a little tool to produce images like this in reasonable time. You can download the code here, and the rest of this post is a quick tutorial on how to use the included command. Maple 11 is required.

Do you have some suggestions on how to do this?

I really seem to be having a lot of trouble with Maple that I don't have with Mathcad and I'm hoping you guys can show me what I"m doing wrong. the issue is that I'm trying to graph more than one curve on a grap which is very easy to do in Mathcad but not obviously so with Maple. My teacher told me to setup variables for each function and then use the display property to show the graphs and this works most of the time but then sometimes it does nothing at all but print the functions verbally. here is an example: restart; with(plots): g1 := implicitplot( 4-(x-2)^2): g2 := implicitplot( x/2 ):

The CDF function permits you to get a probability, given a random variable x. But how do I get the random variable x, given the probability? I have tried using the solver to do this: df := 29: chiSquare := RandomVariable(ChiSquare(df)): solve(CDF(chiSquare, x) = .95, x) But this code only returns the following warning: "Warning, solutions may have been lost" But even if the code did work, using a numerical solver for this kind of thing sucks. Surely Maple has a routine that does a revesre lookup? Can someone please give me some pointers on this? Jim Cicon

Hello, Does anybody know if there's any way to display a 2-D plot & a 3-D plot on the same axes? I tried using display and I got the message: Error, (in plots:-display) cannot display 2-D and 3-D plots together Regards, Drew

In the example below, I find integers that solve the equation. That solution happens to be nonnegative. But in general, just plugging in zeros may not give me a nonnegative solution. What is a good way to find a *nonnegative* integer solution, if one exists?
