## Arrays and a function......

First off I want to say thanks for answering my previous question. I'm having trouble getting maple to define an array of equal size to a given value, x, and then populate it with the numbers 0 to x. Say x was five, I would need Maple to generate [0,1,2,3,4,5]. Lastly, I need to be able to use each member of the final element individually, so I'm not even sure if I'm having Maple do this in the right manner. So far I've tried: m := proc (n) options operator, arrow; array(1 .. n) end proc; for i to n do m[i] := i end do and all I get is: Error, final value in for loop must be numeric or character.

## Anybody has experience of calculating inverse for ...

I'm working with inverse of a complicated matrix, which is 12*12, and all the elements are symbols. I included that matrix at the end. The program is running forever, no results, no error message? Anybody has such kind of experience, any suggestion that what I can do? Thanks a lot, I appreciate your help! Matrix([ [a+b+c+d+e,a+b+d+w*e,a+b+d+w^2*e,a+b+c,a+b,a+b,a+c,a, a,a+c,a,a], [a+b+d+w*e,a+b+c+d+e,a+b+d+w*e,a+b,a+b+c,a+b,a,a+c,a, a,a+c, a], [a+b+d+w^2*e,a+b+d+w*e,a+b+c+d+e,a+b,a+b,a+b+c,a,a,a+c,a, a,a+c], [a+b+c,a+b,a+b,a+b+c+d+e,a+b+d+w*e,a+b+d+w^2*e,a+c,a,a, a+c,a, a],

## How to animate multiple plots ?...

Hi !
I'm wanting to make an animation from images. But these images are not plots, they are lists of plots, which I display simultaneously using the display function. So I've a list of list of plots, which I want to be displayed as an animation. The syntax is animate(function_that_returns_a_plot, ...), and I can't return a plot, since a list of plots is not a plot. Does anybody know what to do ?
Thanks in advance :)

## Trouble defining a function......

Hi, this is my first time posting, so I'm not even sure if this is the right place to ask this. But, I'm having trouble defining a function. I'm using the document view and trying to establish Q(variables)= some function and it returns "Error, invalid parameters for inline function." More specifically:

## General Volume and Surface Integrals...

I've been trying figure out how to code up arbitrary volume and surface integrals in Maple. I know that Maple has the VectorCalculus package but there doesn't appear to be a way to specify a volume integral (where the infinitesimal is dV). Also, there doesn't seem to be a way to specify a surface integral without defining the surface in advance (i.e., integrate over S with an infinitesimal of dS). In both cases, I'd like to have general integrals where I can specify the bounds at a later time (e.g., inert integrals). I know that there is the triple integrals in the student package but they aren't the same as a volume integral.

## How to code the double integral ?...

Dear all : I have a function qx(x):= 1/21 x in (20,40) = 0 others ; My double integral is like integral ( integral (qx(x1), x1=x-10..40)*integral(qx(x1),x1=x-20..40)*1/20, x = 20...30); since the qx(x)'s is not keep constant on whole range, I am confused with the double integral. Any help is appreciated. Thanks

## Help in code usinf lists...

I have two lists viz. X:=[a,b,c,d,e,f,g,h,i] of size 9. And I:=[1,2,3]. I want to generate a list of all the possible patterns of size 9 which can be made using 1,2,3. For example a few patterens which the code is to produce, among many others, are as follows: [1,1,1,2,2,2,3,3,3] [1,2,2,1,2,2,1,2,2] [2,3,3,2,3,3,2,3,3] [2,2,2,2,3,3,3,3,3] etc. Your help would be a great great help to me. I need it direly.

## Functions involving Vector and Matrix entries...

Hello,

Here is my problem:

> vec1:=Vector(2): plot(vec1[floor(x)], x = 1 .. 2);
Error, bad index into Vector

The above should give the zero plot, but it gives the error message.

Of course, vec1[floor(x)] gives the correct answer for any specific x. (i.e. vec1[floor(1.5324)] gives 0, which is correct).

I get the same problem when plotting or integrating functions that simliarly depend on Matrices. What's going on?

Sincerely,

## How to extract functions of specific variable...

I'm looking for a method to extract the (unique) functions of a specific variable from a sum of functions, for example from u=sin(x)*sin(th)+sin(x)^2+sin(2x)+sin(th)^2+exp(x)+x i want to extract for x unique functions = {sin(x),sin(2x),exp(x),x} and for th unique functions = {sin(th)}. For a sum of only trigiometric functions, I use indets(u,trig(x)) and indets(u,trig(th)). However, for a sum of general functions I have no clue how to do this. Any help is welcome. Niels.
