I have the following matrix solution problem. A-1 * C * D-1 * A * v = v where C is a square matrix (integer values). A & D are diagonal matrices. (A-1 and D-1 are inverse matrices) The diagonal elements of D are the column sums of the matrix C. The diagonal elements of A also are integer valued). v is a vector of variables whose values I want to solve for. I cannot figure out how I can get Maple to do this. Do I need to use some other software? It seems to me that I should be able to obtain a soltion to the problem. Is there a reason why there may be no solution? Thanks.

As most of you have probably experienced, even Maple 10.4 in standard 2D Maple input has some strange editing behavior. Most of it is of the variety of "What you see is Not what you get". There are two basic kinds of things that can happen: (a)You get strange errors that seem impossible from the code that you can see, such as "missing operation" or "object used as name" or even "non-matching delimiters"; and (2) Your editing action happens much further away or much more extensively than your cursor position or highlighting would indicate. This apparently happens because Maple is creating a parsing structure on the fly behind what you are editing and not visible to you. When some incomprehensible errors happen or Maple seemingly does not want to allow you to edit what you see is wrong, sometimes the only remedy is to retype whole blocks of code (possibly creating other errors in the process requiring the same cure, etc., etc.). Till Maple can supply us with a structural viewer that would allow us to easily find and correct such problems, I want to pass along some tips I have learned in my frustration.

Hello, I would like to use the solution of an ODE as a function in Maple. For example: ode := diff(y(x),x,x) = 2*y(x) + 1: dsolve(ode); The result, returned by Maple: y(x) = exp(sqrt(2) * x) * _C2+ exp(-sqrt(2) * x) * _C1 - (1/2) Now my question is how can I use this result as a function for calculating for example y(1). Thanks for your help JanE

Will maple show Plank's constant "hbar" as one letter not three letters in 2D output?

> restart;

dotpro := (psi,phi,L)->int(evalc(conjugate(psi)*phi),x=-L..L);

dotpro(exp(I/hbar*p*x)/sqrt(2*L), exp(I/hbar*q*x)/sqrt(2*L),L);

I recently installed Fedora Core 5 (64-bit) on a new multi-pro server (AMD Opteron chips) that my colleagues and I are planning to use for some of our research work. One of our preferred applications is Maple. We recently site licesned a netwrok version of Maple 10, and proceeded to start the process of installing it on our new machine. In advance, I googled 'Fedora 5' and 'Maple', and discovered that a lot of folks have had problems with the installer .bin becuase the installer tries to set the environment variable LD_ASSUME_KERNEL=2.4.1 Well, news flash for Maplesoft - more and more kernels no longer support this bakcwards compatability (including RHEL 5, and Fedora Core 5, and I'll guess Suse 10, and a lot of other distros using the 2.6.x kernel).

fsolve fails when eqs are 2D integrations

hello,
im tryig to install maple 10 on my suse 10.1 system. I allready edited the bin and replayed the "e" of the first "export LD_ASSUME_KERNEL" line with a "#".

The installer installed after that but there are no files in my maple/bin folder... so i dont have a chance to exectue a file...

thanks
Dennis

I'm new to this forum so I hope this is the right board to post this. I've been using Maple in windows for a few years, I usually only use Maple classic. Recently I installed SuSE 10.1 32bit (kernel 2.6.16.21-0.13-smp) on my desktop (dual core Opteron 165 with 2GB RAM), and I installed Maple 10 Linux version onto it. The problem is that the Maple classic often takes 30 seconds to 1 minutes to load some .mws files , while in Windows these files can be opened in 1-2 seconds. I've tried to upgrade to Maple 10.04, and the problem remains, and I noticed that after I typed "xample -cw" in the terminal, there is a message shows "only the first 8192 fonts would be catched"

Hi, I'm trying to use 'numeric dsolve' to solve a system of differential equation. dsol:=dsolve(sys,[phi(t),phi1(t),psi(t),psi1(t),theta(t),x(t)],numeric,output=operator) Now I need to substitute the solution obtained for the unknowns into another expression. What would be the best way to do it/ or what should the output format be? Any help or suggestion will be highly appreciated. Thanx, Priya

Since doing the upgrade for Maple 10.05 (build ID 235106) I have experienced long delays after scrolling in addition to kernel connection problems I described in a previous post. With a 2 page file in document format, I get a delay of over 1.5 minutes after scrolling up the page. This has rendered my copy of Maple unusable in document format. Has no one else experienced these problems? Is there a fix or a way to return to the previous version of Maple?

Yesterday I downloaded and installed the latest upgrade to Maple 10.05 for OS X. Today I find that I can open two worksheet sessions, but not a third. Opening a third file takes ages (approx. 30 sec) and when I try to execute the file, I get the message "Waiting for kernel connection." This behavior is consistent over several tries. I have a Power PC with 1 GB SD RAM. Has anyone else seen this behavior?

I have a list of coordinates that need to be used to create 3d polygons. I need only the outline of each polygon to be graphed (no fill) so that I can see the placement pattern of a line traveling through the polygons. Is there a way to do this? I've tried using polygonplot3d and listplot3d, but neither provide the graph I want.

Thanks!

Hello; I am not sure how to graph a sinusoid. Example: y=A+B sin (theta - D) How do you make a theta? graph: y=10 +5 sin(0theta+30degrees) graph: y = 2 - 3 cos( theta - 45 degree) Thanks; MC

Hello, I am trying to plot a surface with Maple and could not figure out the right way. The surface consists of two pieces seperated by a inequality and it is defined by the following given functions and inequality: x = f(s) y = g(s) if y
