hi

can you help me "i need maple code to solve poisson equation by multigrid method"

thanks

Hello, I've recently started using maple 13. I am working on a project for school where I am attempting to use several independent variables to try to predict a single dependent variable. The nature of the project is that there is currently no known answer, and therefore I have been using regression analysis through maple on each individual independent variable on the dependent variable. I was difficult to find a way to preform a goodness of fit test on the data through maple, but I eventually saw a way on this site to compute the R^2 value.

I need help on turning this code into a procedure and what changes do i have to make  so it works like the gauss-seidel algorithm. I have tried many times on my own but can't seem to get my head around it. Any help would be appriciated greatly.
 

First of all: I'm so sorry, I posted my question to a wrong place ( into the poll).

So I copy here the question and the answer of jakubi and my reply to jakubi.

Question:

I would like to solve the following system

x*(2*sin(x)*y^2+x^3*cos(x)+x*cos(x)*y^2) = y*(2*sin(y)*x^2+y*cos(y)*x^2+y^3*cos(y)),

-x*sin(x) = y*sin(y);

Until I have founded only the solutions

x = k*Pi,  y = +/- k*Pi;    k is any integer.

jakubi's answer:

more solutions

How can I get Maple 10 Standard Worksheet to plot with vertical logarithmic axis having the gridlines at 10,10, and so on, in a vector graphic file like eps?

I am trying to maximize a concave function and I have 6 different parameters. I use the maximize command and establish the relevant constraints. The result I obtain is numerical, but I would like to have an analytical solution with one of these parameters being the dependent variable as a function of the others.

Can I use the maximize command or any other command that will give me an analytical solution instead of a numerical one?

Thanks.

Could I please get help with this maple assignment? No idea where to even begin!!

I use maple sovle an optimality question with hamilton function, but the results are quite different from the given result using matlab. I do not know where I'm wrong ,so can anybody help me ?

Thank you very much!

for what value or interval of p (-infinity < p < infinity) the following is valid

(1+x)^(m+1) > (1+x^m)* 2^m

here x > 1
