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?

How to assign value to matrix in procedure?

with(ArrayTools):
kontraHom := proc(M, s)
dim := Size(M);
n := dim[1];
m := dim[2];
R := [][];
for i from 1 to m do
    for j from 1 to s do
        for k from 1 to n do
            R[(j-1)*n+k,(j-1)*m+i] = M[i,k];

I'm running simulations in which I produce many plots at once, the purpose being to compare differences as parameters are changed. I'd also like to use some of these plots for publication. I've had problems getting good-looking 3d plots. Here's a strange thing I noticed.

Export the graph by mouse-clicking, export to bitmap:

EDIT : IMAGE POSTED IN MY COMMENT BELOW

Export the garph by executing a plotsetup('bmp') command.

1. How many and which file format can be used to save a list of formulas?

2. how to append to above file?

i would like to let c# program to read the formula in the saved file
