## Document Block Output Suppression Problem...

I am attempting to use document blocks to hide the Maple code for an interactive document and I'm encountering an unbelievably frustrating issue: if I create a new document block and suppress the output of the function calls therein with a colon, when I collapse the document block, the function calls are not hidden at all, but are displayed in a continuous line. If I do not supress the output, once I collapse the block, only the output is visible (which may be desirable except that I am doing things like loading packages, storing plot3d and plot variables, etc., and I DO NOT WANT THE OUTPUT VISIBLE).

## Define function with matrix perhaps?...

I'd like to define a function f(a,b)= product(product(p(a,b,c[i],d[j])^x[ij]*(1-p(a,b,c[i],d[j]))^(1-x[ij]),j=1..n),i=1..n) (The x's are known data, each 0 or 1, the c's and d's are also known.) Is there a way to do this without writing it out long-hand, say using a matrix of the x's and vectors of the c's and d's? Thanks.

## Indexing piecewise functions?...

I have an array of functions involving x such that array[i] is valid only on the interval x=i..(i+1). I am trying to create a piecewise function that includes all array[i] terms valid in their respective ranges, but I am running into some syntax problems.

## I can't integrate this...

Hi! I am new! I can't integrate this... could u help me? (exp(-1/2*(ln(y)-(x*b+2))^2/(sigma^2*(x^2+1)))/(y*sigma*sqrt(2*Pi*(x^2+1))))*(2-1.666666667*x), x=0.6..1.2, y=3.6..4.5

## how to solve a system of equations and inequalitie...

Can any one of you help me to solve the question below? Please... Question: Find non-negative integers solutions that satisfy the following conditions: Given: p,k,h,a,b,c are integers. The conditions are: (1) a+b+c=k*h-h-h*h+1 (2) (p-k+h)*(p-h-1)*(p-1)-(p-k)*(p-2)*(p)=a*(p-1)+b*(p-h-1)+c*(p-k+h) (3) h>=1 (4) h

## Classic Worksheet Mouse sensitivity problems...

Hello All!
When using Maple 10 Classic Worksheet, the mouse sensitivity goes up tremendously, making it really annoying to work with. The sensitivity is only increased in the Maple window when it's activated. I only have this problem with Classic Worksheet, but it's the 'version' I use. Is there any workaround for this? Like some sort of registry fix?
I'm using a Logitech Mx500, by the way.
Any help is really appreciated!
Cheers

## Memory and evaluate...

Hi, I have a very problematic question. I have a Matrix (100 x 100) that contains complex numbers express as symbols. The numbers derive from several operations. I want evaluate the Real part of the complex numbers for successive calculus but the software show a memory problem. How can I do? I have a P4 with 2GB of memory. I use the function: map(Re,matrix); Thanks

## Exporting figures as Encapsulated PostScript files...

Greetings! I plot a 2D standard figure in Maple 10. I select the figure, right-click it and choose "Export as". The file format I want is Encapsulated PostScript files (.eps), which is one of the alternatives. I save the figure as an .eps file in a map. Everything works fine until I import the file in Scientific Word. The figure is imported all right, but has been rotated 90 degrees counter-clockwise. I do not know how to rotate it back. I know there is a package in SW that enables rotating, but I can't get it to work. Is there something I can do in Maple to correct the problem? Is it a common problem for other users and how do you solve it?

## A Procedure with process launch...

Hello, I'm trying to make a wrapper procedure that will launch an external program with some dynamic arguments. To do this I created a proc and used the launch command from the process package. My procedure seems to be syntactically correct, but when I run it all it does is echo the procedure code. Since nothing was working I have created a simplified procedure that simply tries to launch Notepad. Instead of launching notepad it just echos out the source of the procedure: My definition of the procedure RunNotepad: ``` > RunNotepad() := proc() > use process in > launch("notepad.exe"); ```

## Dominant Eigenvalue...

Hi, It's quite easy to find the eigenvalues of a matrix, but is there a function to find the dominant eigenvalue ?
