I suppose this should belong in a blog or a post but it's more of a question because I don't present anything, but I merely pose an interesting question and wondered if anyone was up to the challenge.  This is also related to Deconstructiong a wave http://www.mapleprimes.com/questions/124373-Deconstruct-A-Waveform-Into-Its-Fundamental

Recently I read an interesting...

What is the equivalent command from the MATLAB conv in Maple?

Convolution and polynomial multiplication

convolves vectors...

Maple 14:

1, i can't "tab" anymore.

my tab key is turned on(otherwise when i press tab, the curser goes to the next "section"), when i press tab, the curser simply moves over a tab but the words don't! and sometimes when i press tab, nothing happens, and often times, things start to get really buggy and weird.

2, i have to "enter" my module twice before it will work...here is what happens:...

Hi everybody,
I have these two (three) animations (a single animation and a array with two other animations) and I would like to plot the three animations such that when I click on the play button of one of them, all the three animations starts at the same time.. I don't know how to get this, please help me if you can!
This is the code of my animations that I'd want to run at the same time:

The first:


display([mech||(2..nstep+2)],insequence=true,gridlines=true,title="Mechanism...

s:= int((1/4)*sqrt(2)*exp(-(1/2)*(x+k*sin(-theta+phi))^2/sigma^2)*(1/(2*Pi)+Q*cos(k*phi))/(Pi^(3/2)*sigma), phi = -Pi .. Pi);

how to use reduce command to get prime ideal?

i find PrimeDecomposition and PrimaryDecomposition in package with(polynomialideal):

is the primedecomposition for prime ideal?

any command same as http://www.singular.uni-kl.de/Manual/3-0-4/sing_244.htm

Can anyone explain why I get a different answer if I use int instead of Int in the following evaluation:

> evalf(subs(r = 1, Int(Int(Dirac(x1+x2-r)*q, x1 = 0 .. 1), x2 = 0 .. 1)));
                                 1.676209155

> evalf(subs(r = 1, int(int(Dirac(x1+x2-r)*q, x1 = 0 .. 1), x2 = 0 .. 1)));
                                     0.

Currently, the size of a table/matrix which can be exported to a spreadsheet is limited to 255 columns X 65535 rows. I believe this rule was implemented because of the maximum possible size of a spreadsheet(Am I right?) . This used to be the case in Excel 2003, but since Excel 2007, a spreasheet  can be : 1,048,576 rows by 16,384 columns.

Maybe it is time to update this rule?

hi, i have a function in seri's with one unknown parameter and i want to solve it for this boundary condition : f(infinity)=1

I use pade approximation but in my case it doesnt work. i want to know is there exist other  method in maple for this problem. for example other rational function.

thx

for simple case 2*2,  A = matrix([[0,-1],[1,0]]);

using A, i understand f(x,y) = f(-y,x)

where do other case f(-x,-y) and f(y,-x) come from?

any command to list all cases with input a matrix A?

if A has more dimensions, what will the cases be ?

Hi , how do I get the binomial expansion of  1/sqrt(9+4*x^2) .  I am using expand(expression,binomial) . But Maple just

returns the expression.  Thanks .

how to x1, x2 ... with xi in procedure?

b := 1;

for i = 1 to 3 do

     b := b*1/(1-xi);

od;

but xi can not represent x1, x2, x3, which commands can present x1 x2 x3 ?

which package containing command to find prime ideal and quotient of ideal?
