I am having a problem with variable assignment.

output 15 should be:

test :=[1]

[2]

[1 1]

At some point, the array test is being overwritten even though in my proceedure I use only local variables.

How does one go about defining a road surface that can be used with the tire library for doing road holding on hills and side slopes?

> I found this information and code quite useful. Now my set t1 changes slightly to include I and -I. I also set up conditionl statements to extract the right elements according to the criteria on the value of beta*Q as adviced previously. I then test this out using the values for (beta,Q) as (1,1), (-1,1),(0,1).

When beta*Q is positive (one in this case) I is not selected...

I'm looking for a quick way, preferrably without using any loops to 'map' a function using several vectors.

In the single vector case, this is quite easy, but with multiple vectors, I'm not sure if map is the correct command to use.

For example:

u:=<1,1,1>;
v:=<2,3,4>;

f:=(x,y)->ln(x-y);

What I'd like to do is create a new vector from the map of the function onto both vectors,...

Dear All,

I'm a beginner who is learning Finite Field under the help of Maple. I'm wondering is there a command to compute the minimal polynomials for the members of a finite field?

For instance, for GF(16) realized by the polynomial a^4 = a + 1,we know that for a's minimal polynomial is x^4 + x + 1, a^3's minimal polynomial is x^4 + x^3 + x^2 + x + 1. In Maple, how do I reproduce such result?

Thank you very much for your help,

Best,

Kelvin

I am a newbie in Maple.

I am trying to evaluate and to display the electric field with Maple in Document Mode.

I have several questions:

1. How to delete errors from prevous calculations?

2. How to delete formuls from previous calculations?

3. How to wirite vector functions?

4. How to evaluate vector funcitons?

5. How to display 3D plot of a funciton?...

Hi! Normally recursively defined functions work well, but if I use a sum inside, this happens:

> y:=n->sum(y(k),k=0..n-1);

I need to send a Maple worksheet (.mw) to someone who is not a Maple user,doesn't have Maple installed.So what is the simplest possible solution now?How can I convert this into a pdf/doc/ps/eps  file so that any document viewer can open it?

Hi,

I'm having some troubles in solving an equation which has the following form:

S. Inv(R). T = L

whereas S is a [nx1] row vector, T is a [1xn] colomn vector, R is a [nxn]Matrix and L is a scalar.

The problem is that R is a quite complicated function of a single variable for which i want to solve this system. Thus the analytical matrix inversion doesnt work.

Do you have any suggestions how i can solve this in a numerical way?...

Hi, Can Maples Logic package solve these problems?

How can they be formulated and solved in Maple? rgds

Let's say that the following arguments are true: Some gatekeepers are warriors. Some warriors are cowards. Therefore, we can conclude that some gatekeepers must be cowards. Is this conclusion true or false? answer: F

 Let's say that the following arguments are true: All Parkers are Franks. All Franks are smart. Therefore, we can conclude...

Hi, I would like to fit my data with a physical model. Unfortunately, I have the model in the form of an ODE which can be solved numerically only. So made a procedure output as follows:

I solve one task. And as a result I receive a matrix and export it to a textfile. Then I receive another matrix and try to export it to the same textfile. Another words I need to add a last matrix to previous one but when I use exportmatrix command the last matrix overwrites previous one. What can do?

Hi, dear mapleprimes. These days I'm preparing my thesis. I use maple to generate some figures, and save them as .jpg. These figures are very clear when I insert them into a word document (my thesis). But after I print the document, the figures looks unclear. It seems that they are cuted from other papers, but actually they are not.

I think it is important to print clear figures, I want the figures can be printed clearly...

Dear guys

I have a set of ODEs but when I solve it maple shows this massage:

"Error, (in dsolve/numeric/SC/firststep) unable to evaluate the partial derivatives of f(x,y) for stiff solution"

If I neglect the option "stiff=true", it works but then when I want to plot something maple says:

"Warning, cannot evaluate the solution past the initial point, problem may be complex, initially singular or improperly set up"

and only shows a coordinate...

Good afternoon

I don´t know if a principal worksheet in maple can call other secundary worksheets.

Please help me. I don´t know the code, or function
