Maple 11 on linux so far has been fantastic, but there's a problem with printing. I use cups, and every other application brings up its printing information just fine. When I try to print in Maple, it gives me an error that says "No print service found". Does anyone know how to deal with this?

We seem not to be able to run Maple 10 properly on our Uni network. The problem is that users can not save preferences or use the Compiler. It seems the problem is due to poor programming practice by Maplesoft, although the issue is obscure and I am prepared to be convinced that the problem is our Computing Service's implementation of it. The problem is (I believe) this. Our system is as follows (under XP Pro): All users and PC's live in our Active Directory and all software is applied via group policy. Users have roaming profiles (which are not backed-up!) and their 'Start menu' and 'Desktop' are redirected to a 'read-only' server location

Just wonder if anyone knows how I can improve on minimizing this large poly, subject to constraints: Download The minimum found was 82.7 It has found a local minima, but there must be a global minima. Do i really have to splash out on the GOT package?

Hello, I would like to use Maple instead of Matlab, well I rewrite the Matlab code to Maple like following. The output is correct, but it spends more time than in Matlab. Is it possible to rewrite my Maple code to get output faster? restart: linearni_model:=proc(beta,sigma) local n1,n2,Y,X,Y1,Y2,se,se2,t1,t2,t3,t4,vbeta,t,si2,e1,e2,e3,e4,Yp,N,s2,n; use Statistics in X:=Matrix([[1, 1, 1, 1, 1], [1, 1, 1, 1, -1], [1, 1, 1, -1, 1], [1, 1, 1, -1, -1], [1, 1, -1, 1, 1], [1, 1, -1, 1, -1], [1, 1, -1, -1, 1], [1, 1, -1, -1, -1], [1, -1, 1, 1, 1], [1, -1, 1, 1, -1], [1, -1, 1, -1, 1], [1, -1, 1, -1, -1], [1, -1, -1, 1, 1], [1, -1, -1, 1, -1], [1, -1, -1, -1, 1], [1, -1, -1, -1, -1]]);

Hello, I would like to use sum command to compute sum. > A := Matrix(3, 2, {(1, 1) = 1, (1, 2) = 2, (2, 1) = 2, (2, 2) = 3, (3, 1) = 3, (3, 2) = 4}); > sum(A[k, 1], k = 1 .. 3); Error, bad index into Matrix Why it occures an error? If I use sum over list, it works. How can I sum members of 1st column of Matrix? Thanks Vladimir

Hello, Can someone please help me with entering an if statement with the decision: if (x is between A and B) and if (y is less than C) then ... end if end if I am having trouble evaluating an if statement when the argument lies between two constants as well as incorporating an additional logic check. Thanks, Ken

Hello, I want to rewrite the following Matlab code to Maple sum(Yp.*X(:,2)) and si2(:,1)=1/2*(Y1(:,1)-Y2(:,1)).^2; Could you help me please? Thanks Vladimir

Does anybody know how to move the legend in the ploting area? By default, the legend sits at the bottom and outside the plotting area. Thanks.

I used Maple10 to solve an ODE from my research project and got a solution with HeunC function. I did derivative of the HeunC function and got HeunCPrime function. However I found HeunCPrime is just a sign. It cannot be valued or plotted with a selection of parameters. My questions are as follows: 1. Is there any special package I need to use to value or plot HeunCPrime function? 2. Is it possible to convert HeunC into other functions which I can manipulate for derivative and plotting?

Here's something I think TPTB at Maplesoft should be aware of. In MAPLE10, when you type ?while you get an explanation of 'while' statement used in conjunction with the 'for' statement - you don't get an explanation of the 'while' loop. For that explanation you have to go to the books. Perhaps this is corrected in MAPLE11.

I was wondering if anyone might know how to print the intermediate steps when using the dsolve function in to solve a 4th order ODE. I get the result of the dsolve function, but I want to see the actual steps that maple takes to get there. Is this feasible at all, or is there another much simpler method that I'm just not finding? Thanks in advance Jimmy Navarski

Does anyone know how use the command VolumeOfRevolution so that its plot output shows an n number of disks, instead of a continuous surface? The Volume Of Revolution Tutor allows one to specify if the output plot is in the form of a continous volume or with disks, but I can't get disks to display work from a worksheet. Thanks, Phil

Dear Sir: I try to learn to use the linear algebra in maple. I try to compute the following matrices. restart; assume(a>0,b>0,c>0); with(LinearAlgebra): M:=Matrix([[a, 0],[0, b]]); K:=Matrix([[c,-c],[-c,c]]); V:=Eigenvectors(K,M); X:=V[2]; Multiply(Multiply(X^%T,M),X); I expect that the final result should be the indentity matrix. However, it does not produce what I expect. Please give me some advice to get the identity matrix. Thank you.

It should be ~ -27700/841-21375/841*I as floats with good exactness.
