When using the Plotter element in a Maplet, one of the options is (copied from the help file):
delay = posint
The delay in milliseconds between frames. The default value for this option is 100.
So far, if I set this above 1000, the animation will not play. 1000 works and anything below it. Does this mean I cannot have my animation play slower than one second intervals between frames?
If this is the upper limit, does anyone have a suggestion for how to get around this? One thing I was thinking was using the Student[Calculus1][ApproximateInt] command (this is what I'm animating) with the partition value set at different intervals corresponding to a function, t, 2*t, 4*t, etc., just like the actual animation does. But I could have my plotter updated manually using a time delay function that Will gave me previously on here. That's a lot of extra code, though; delaying the plot speed even more would work much better.

Hello!
I have two questions:
1) If I include the package
\usepackage[latin1]{inputenc}
in the preamble of my latex file, I got an error. Is it possible to circumvent it?
2) When I'm writing Maple questions (\begin{question}{Maple}...), and when I use de edu translator I also got some errors. Any help?
Thank you very much.
Gaspar.

i've been trying to evaluate this particular expression:

restart:

assume(x::real,0<x,x<1); is(x < tan(x);

and I keep getting a FAIL. Any ideas? is there something i'm not assuming? not enough info?

Given an implicit representation of a 3D surface, for example:
1 = 3/(z^2+3)*exp(-1/2*(3*y^2+2*x^2+x^2*z^2-2*y*x*z-12)/(z^2+3))
does Maple have a function to numerically integrate its volume? I was hoping to avoid the nuisance of computing the bounds on x,y and z myself and then performing the triple integration (I tried this, but the third integral hung Maple up...I gave up after it ran for 24 hours).
The implicit plot seems to work fine, which shows a nice blob. This should be fairly easy to integrate...
Thanks,
Matt

I have a maple worksheet (attached) that calculates a 2-D convolution. Should be easy, I would guess. The convolution of a gaussian and a gaussian is very fast-- this has a simple analytical result anyway. A gaussian and a sinc function can take a couple of minutes... and a gaussian and a bessel function takes longer than I can allow! I think I must be missing something here. I've tried various things, interchanging "int" and "Int" for the integration, and also seting digits to something low, by using evalf[4]. Sometimes it just maxes out all available memory before grinding to a halt, in other trials it will allocate about 300 MB and churn for hours. The worksheet is attached. I'd appreciate the advice.

Hi,

I am trying to ease my c coding work with the "CodeGeneration" tool in maple. The Idea to generate ready to use functions is quite thrilling.

In my attempts to generate code I entontert two problems.

First it seems to be impossible to assign local vectors to vectors passed in the argument list:

> MapX := proc (X\_out::Vector(2), X\_in::Vector(2), PRO2RO::Vector(2))

> local X\_t :: Vector(2,0), i;

> X\_t[1] := PRO2RO[1];

> X\_t[2] := PRO2RO[2]*10;

> X\_out := X\_in + X\_t;

> return;

> end proc;

here the assignment X\_out := X\_in + X\_t; is not recognized.

Hello everyone,
I am trying to create a procedure to translate a matrix into a nested list. (in Maple 10)
I actually want to transform the matrix
A[i,j] whose indexes are in the interval i,j=1,2,... d^k
in a list:
L[n1,n2,...,n2k] whose indexes are in the intarval
n1,n2,...n2k = 0,1,2...,d.
For instance, a transformation of indexes could be:
for i from 0 to d do
for j from 0 to d do
for k from 0 to d do
for l from 0 to d do
L[i, j, k, l] := DM*([1+(sum(d^(i-1)*n[i], i = 1 .. k)), 1+(sum(d^(i-1-k)*n[i], i = k .. 2*k))])

But I would actually like to indtroduce k and d as parameters of the procedure. My problem is then how to say:

Hi All,
I'm wondering if anyone can advise me on ways to perform 3D trapezoidal interpolation in Maple. Using 40 experimental data points View 2213_090606_PleaseHelp.mw on MapleNET or Download 2213_090606_PleaseHelp.mw, my goal is to generate a figure like the one on the right here:
That figure was generated manually by a colleague of mine (he drew in the triangles himself), but I'm wondering if Maple can do something like this. Thank you very much for your time!

Hi;
Is there any way to find
int(x*exp(-I*x*theta)/sinh(1/2*Pi*x),x=-infinity..infinity);
by maple, where theta is a real constant.
cheers

I know using partial_diff can do Grad of a rank 1 tensor (i.e. vector) and get a rank 2 tensor. How do I do the reverse? is there any simple way? Thanks

We use maple to generate all of our computational bits, dump this out to header files, and include this in our code base. A lot of the code that is generated is redundant so it would be nice to have codegen[C] know, or at least be able to be told, to optimize the entire code being dumped to the same header file. Is this possible? Examples follow...
"
.....
DCb := array(1..3):
lp:='lp':ip:='ip':m:='m':ap:='ap':jp:='jp':a:='a':l:='l':j:='j':i:='i':k:='k':kp:='kp':
for ip from 1 to 3 do
DCb[ip] := sum(sum(sum(sum(sum(gd[ip,jp]*gu[ap,lp]*jacu[m,lp]*jacu[a,ap]*dJ[jp,m,a],m=1..3),jp=1..3),lp=1..3),ap=1..3),a=1..3):

I have a problem with a sentence that I have. I don't know whether it is a formatting problem or problem with the statement itself. I'm trying to say something like this (if it makes it less abstract, I'm trying to formally define a Sudoku puzzle).
For any set S and function F that maps the ordinal set |S|^2 to |S|, there exists a set T which is a subset of S^|S||S||S| such that any element of T Tabc is equal to the empty set iff c !=F(a,b)
First of all, theres a couple issues with this. |S| is the cardinal of S, but for convenience I also use it as an ordinal set. Second, as I started typing this I saw that I do not have the necessary statement for all Tabc which are members of T. How can I correctly input this statement into Maple?

Hello,

Please help my with my program. First, I'll post the relevant code, then the questions:

--------------------------------------------------------------------------------------

with(Statistics); with(LinearAlgebra);

#k is a Vector everywhere in this program

ModeFreq := (k, m)->Norm(<Norm(k, 2), m>, 2);

OscillatorAmplitude :=(n, k, m, x) -> (ModeFreq(k, m)/Pi)^(1/4)*exp(-1/2*x^2*ModeFreq(k, m))*HermiteH(n, x*sqrt(ModeFreq(k, m)))/sqrt(2^n*factorial(n));

DeltaApproxAmplitude :=(x0, N, k, m, x) -> evalf(expand((sum(OscillatorAmplitude(n, k, m, x)*OscillatorAmplitude(n, k, m, x0), n = 1 .. N))/sqrt(sum(OscillatorAmplitude(n, k, m, x0)^2, n = 1 .. N))));

I am trying to familiarize myself with the functionality of the Maplet Builder, and I'm having some frustrating problems. Whenever I set a button to change the value of a MathML viewer, for the command, I use the statement MathML[Export](insert Maple statement here), and I receive an argument error. In addition, I was wondering if (while using the builder) there was a way to add some code that evaluates one or more Maple statements (i.e., variable definitions to be used by multiple Maplet components,etc.) that *does not* affect the value of any of the component properties. I'm used to using the GUI components in worksheet mode which seem to be more flexible in terms of programming actions for components (perhaps only because of my ignorance pertaining to the Maplet builder).
