Hello,

I have started using Maple and I was computing some algebraic  system of equations and when Maple solves it it returns nothing. I do not understand what is happening. Does it solve it but for some reason does present the result or it does not solve it. Because simple systems it solves and shows the result but for my system it does not show anything...

My equations are:

eq5:= (((Nd)^((epsilon-1)/epsilon)+Fu^((epsilon-1...

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:

refer to Madan's paper about VG in year 1998

equation (6)

tm := int(expand(1/(rho*sqrt(2*Pi*g))*exp(-((X-theta*g)^2)/(2*g*rho^2))*g^(t/v-1)*exp(-g/v)/v^(t/v)/GAMMA(t/v)),g=0..infinity);
characteristicfun := invfourier(int(tm,x=0..infinity),x,w);

it is not equal to (1/(1-i*theta*v*u+(v/2*rho^2)*u^2))^(t/v) ?

it can not be calculated

I would like to create a single animated plot with two components.

The first component being an animation of the graph of r = 2*sin(theta) as theta varies from 0 to 2*Pi in the r-theta plane.

The second component is another animation, simultaneously showing how the graph of r=2*sin(theta) is generated in the polar coordinate system.

I am able to produce each component separately rather easily using the plots:-animate( ) command. What I am looking for is somehow being able to use ...

Hey guys

I am currently working on my final project in high school. This project is about mathematical modelling within epidemology, and i am currently working on the mathematical models based on the SIR model.

The basis models for the SIR model were pretty easy, but i cant figure out how to fit data to my models. My first idea was to use the method of Leastsquare and/or Nonlinearfit, but i cant figure out how to do this in maple.

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.

Hi, I've defined a function :

We have just released Maple 16.02 and MapleSim 6.01.

Maple 16.02 includes updated platform support, enhancements to the Physics package (including fixes to problems first reported on MaplePrimes - thank-you),  connectivity to the latest version of MATLAB and Visual Studio , as well as some efficiency and interface improvements. See the Maple 16.02 update page for more details.

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); 

I have a large symmetric square 15x15 matrix (say B). With all entries in the region 0.285746383 and I am trying to calculate the eigenvalues of them using

with(LinearAlgrebra);
Eigenvalues(B);

B was originally an array that I converted to a Matrix with convert(B,Matrix).
I have also used type(B,Matrix) which returns true.

Yet when I enter Eigenvalues(B); It returns "Error, invalid input: LinearAlgebra:-Eigenvalues uses a 1st argument, A, which is missing"

I have several functions that cannot be integrated analytically but are to be used (repeatedly!) in further integrations. I have created a table of values of these integrals for a mesh of parameter values.   If I then use the ArrayInterpolation function to compute just one value at one point - it's very inefficient - takes lot's of time...  

   What is the optimal way of defining "InterpolatingFunction"  (in the language of Mathematica)?  Are...

Which algorithm does the LinearAlgebra->MinimalPolynomial function use to compute the minimal polynomial of a matrix?

Thank you.

Hello,

I just lost the result of a 20h calculation due to the last-name evaluation using tables. Consider that

t := table([1=2]):

s := t:

save s, "table":

restart:

read "table":

s[1];

evaluates to t[1]. The save command only...

Hi,

I used Maple in my studies, but it is not suitable for screens with high-dpi resolutions and it has no full screen mode.

I have a Macbook Pro Retina.

Thanks.
