correct is genfun2

but using famous hypergeom of charlier written in many books and papers, it can not summation to a correct generating function

Based on past releases, after Dec 31 any hope of a 16.03 update becomes very very slim. 

You see, any last issued updates (back to Maple 11) have all happened before the turn of the new year.  And should we make it into the new year without one last update then we can almost be certain that Maplesofts focus is all on the next major release, Maple 17.

There is always hope, that a few more loose ends can be tied up before the next major release, however...

Hello,

I am working on a project where Maple's output is fed to another software which requires all it's input in specific format. So, I want to print this expression,say

y=+2.*x+.2, in this software, but it takes input as

y=2*x+0.2, So now I have to change

+2. to 2.0 or 2 (if it's starting of the equation)

-2. to -2.0

.2 to 0.2

Is there any way to convert all the numbers in the equation to...

I have come across a missing rule that Syllable length does not take into account.

with(StringTools):

SyllableLength("raked")

SyllableLength("rakes")
                 2
SyllableLength("baked")
                 2

i got two density, the part of it is similar the pattern of gamma, how to convert it into an expression of gamma times something?

test2 := x*Diff(P,x$2)+(a+1-x)*Diff(P,x)+mu*P=0;
Density := int(exp(-X*(I*u-a*i))*(-i*X)^(-a), X = -infinity .. infinity);

test2 := x*Diff(P,x$2)+(a+b-x)*Diff(P,x)+mu*P=0;
Density := int(-exp(-X*(I*u-a*i-b*i+i))*(-i*X)^(-a-b)*i*X, X = -infinity .. infinity);

use the formula provided in

http://en.wikipedia.org/wiki/Hermite_polynomials

and run in Maple

but result is not exp(2*x*t - t^2)

1. I use your previous reply on V_G derive  on other characteristic function, but most are undefined

or complicated solution or can not evaluate, why?

for example

charc := 1+i*X/(i*X-1);
int(exp(-I*X*u)*charc, X = -infinity .. infinity);

it got this complicated thing
piecewise(Im(1/i) = 0, undefined, int(exp(-I*X*u)*(1+i*X/(i*X-1)), X = -infinity .. infinity, method = _UNEVAL))

Density := int(exp(-I*X*u)*charc, X = -infinity .. infinity);

Hi,

I'm running a 2D parameter sweep from Maple 15 on a MapleSim 5 model. The output is stored in a 2D matrix.  I've encountered two problems:

1) when I graph it with matrixplot the z-axis values are fine but I can't figure out how to change the x-axis and y-axis values from the matrix indices to the actual values of the swept parameters. 

2) When the parameter sweep begins I get a warning about storing the values in a matrix.  Maple...

I would like some help in order to build the following algorithm (Gianni-Kalkbrener) on Maple.

I have a cyclic-5 problem of the following polynomials

L := [a*b*c*d+b*c*d*e+c*d*e*a+d*e*a*b+e*a*b*c, a*b+b*c+c*d+d*e+e*a, a+b+c+d+e, a*b*c*d*e-1, a*b*c+b*c*d+c*d*e+d*e*a+e*a*b]

I found the Grobner basis of that using:

GrobnerBasisOfL := Basis(L, tdeg(a, b, c, d, e))

Then, I have found the FGLM of the Basis using:

Hi im using maple 16 and defined a vector field that is lengthy below,

(and yes i defined with(VectorCalculus), and SetCoordinates(cartesian(x,y,z)) (x,y,z is subscripted)

And i am using a type of line integral for the work of a particle's path through a force field which i defined here as Z.

Hello,

I'm trying to fit some of my research data to a polynomial.   I can do this, but what I need to know is how Maple is calculating the standard errors.  In other words. I need to know the underlying forumla Maple is using for these standard errors.

Is there any documentation on this anywhere?  

For reference, the Maple command I am using is:
LinearFit([Z^(-2),Z^(-3),Z^(-4),Z^(-5),Z^(-6),Z^(-7),Z^(-8),Z^(-9)],X,P2,Z,output=standarderrors);

Has anyone seen this form of a nonlinear equation with respect to X, but linear with respect to Y & Z?  I provided a contour plot within the region for all 3 variables between -2 & 2.  The plot is actually Z*conjugate(Z) so that the magnitude is above ZERO.  If I am correct I may have seen this before in orbital mechanics, but my undergrad years are a bit...

H(M) = ker(d_k) / im(d_k-1)

would like to see the example of calculation of H(M) above

I am experimenting with the new AS3 flash questions and everything works as expected except that I cannot load external swf files using a xml file. I have a parent swf file that behaves well, except that this parent swf cannot load the external swf files. It works flawlessly on my own website (which even does not have a cross-domain.xml file in the root directory).

Is there a restriction in Maple T.A. that prevents loading xml files by a swf (and/or loading external swf's in general)?

eqn := y^2 = x^3 + a*x  + b

where a and b are summation of things, or constant

if use convert(eqn, ratpoly) to get a ratpoly

can it be used to guess gf using guessgf directly?

or

convert ratpoly to differential equation and then calculate eigenfunction and calculate generating function?
