Is it possible in Maple to choose the dimensions for a plot? I mean to choose the height and the width of the plot?
For example, to enlarge the plot to the whole width of the maple page? Is it possible?
I need to do this because I have to plot together objects of different dimensions and so the smaller ones look too small, so I would like to enlarge the plot to solve the problem. 

i calculate a polynomial as following

yn := f(x) = _C1*hypergeom([-(1/2)*n, 3/2+(1/2)*n], [1/2], x^2)+_C2*hypergeom([2+(1/2)*n, 1/2-(1/2)*n], [3/2], x^2)*x

want to get the polynomial with degree n  for  summation_n_from_0_to_infinity y_n*z^n/n!

such as n = 1 n = 0 n = 3, but above yn is hypergeom, is n represent degree, if so, i use subs, then is finished, if not, how to get polynomial with degree n?

What is the distance between the trigonometrical polynomials of the form a0/2+a1*cos(Pi*x)+b1*sin(Pi*x) and the polynomials of  degree at most 1, ie c0+c1*x, in the Chebyshev metrics on the interval [-1,1] and in the L^2 metrics on the same interval?

I have a set of nonlinear and coupled PDEs for a cable actuated system. I want to transfer this set to a set of ODEs and write it down in Matrix form. I used Galerkin's method and derived the ODEs in discritized form. I have a problem in converting this set of equation into a matrix form like "Mq"+Cq'+Kq=F". The derived equations are very complicated and contains some nonlinear terms. One of the three equations looks like this:

I have been investigating Predator-Prey spatial models, e.g.

I have a problem.

I solved a problem, but i like to get one solution for one variable.

i send my project.

help me please.21-07-2011_-ecuacion.mw

Hi Dr. Kamel Boughrara,

I have a question,  I know phi = B*A, but in code i can't understand a part of it, can you kindly explain it in engineering terms.  

kindly see the attach file for phi.

Second question

why e-->sum(factor(e(t)),n=1..100), wht this means, 

Hi guys,

I am working on the following pde

m₀=-Bw_ssss+(F_t-Bw_ss²)_s(w_s+r_s⁰)+(F_t-Bw_ss²)w_ss+q

where

F_t=EAe+T₀+p_wgPiD_o² (H_w-z)/4-p_mgPiD_i² (H_m-z)/4

Hi Dr. Kamel Boughrara,

I have question regrding the analytical solution in section 3.3,  I am attaching a file.   Question is regarding  the programming you did, does it has any effect on the solution.  Because i tried to change the values for p, and other variables but could't see the effect.

Also wht the following variable means;

Hi i´m writing a paper about math and i use maple 10 and M. Word 2007 for it, i started with a Laptop with Windows 7 and when i finished it, i open the archive in a desk computer having the same especifications  i notice that the images of ecuations were altered changing "+" and "-" for "C´s" and "K´s", i tried a lot of computers with others especifications and my problem still the same, i changed the format and other stuff but i can´t...

i use symmetric function package

with(SF):

i would like to know after calculating the basis toS(....)

which function can be used to convert into polynomials?

as i expect to get the sequence from any polynomials generated from it

Hi:

I am running a home network, XP and Maple 11 on the old computer, Win 7 and single-user Maple 15 on the new.

It took a long time, but I finally got a wireless network running, so that Win7 on the new computer can open and access all the files on the old computer.

But when I run Maple15 on the new computer and try to open an old computer file, Maple 15 cannot see the old computer or any of its directories, even though it has a "network" tab on the "open" command.

I'm using maple 13.

The expression that I paste below is quite large and subsequent expressions are also swelling. This is causing maple to slow down and in some instances I get a message saying the kernel has disconnected (maple just times out) I want a way to programmatically reduce the size of the output. I have tried simplify(expr,size) and this has helped some. I don't want to use simplify(expr,symbolic) because of the presence of the square roots. Is there...

In coding theory, there are parity-check codes whose parity-check matrices H are generated via column permutations. For instance, the LDPC codes constructed in Gallager's 1962 IRE Trans paper uses the following H matrix:

[ X1 ]

[ X2 ]

[ .... ]

[ Xn ]

where submatrices X2 .. Xn are just random column permutations of X1. However, to make the codes efficient in decoding, there is one restriction which requires that any two row vectors in...
