The best way to do what you want is just to use Maple's default inline output. You shouldn't need to open and close document blocks.

The answer to Maple Equation is Maple Equation

Now if I go back and change the 3 to a 4 and re-execute

Maple EquationThe answer to Maple Equation is Maple EquationMaple Equation

I just edited the numbers and pressed the !!! button in the toolbar, I didn't open the document blocks.

This is what I get when I run your commands:

What is the problem with the plots?

It looks like your problem is that you didn't put brackets around the negative sign in the power.

Adding brackets solves the problem

I wonder if the select function might do what you want?

> ?select

Here is an example

Create a big dataset

> a:=convert( LinearAlgebra:-RandomVector[column](1000), list ):

Create a procedure that will check if the value is in the correct range. We'll look for values between 0 and 10 inclusive

> inRange := proc( x )
if( x >=0 and x <= 10 ) then
return true;
else
return false;
end if:
end proc:

Now let's use select to only get the matching values

> b:=select(inRange, a);

Let's see how it works. We create a random matrix G.

I assigned your Matrices to variables:

Then to output the values I used the CTRL+= keystoke. Hold down CTRL and press =

I entered the following line this way:

For all of your posts, it would be a lot easier for people to help you if you copied the code that links to the files that you have uploaded. You can get this code from the bottom of the file details page, or on the right hand side of the file manager. Here are the links for Georgeworksheet14.mw View 2292_Georgeworksheet14.mw on MapleNet or Download 2292_Georgeworksheet14.mw If you don't put the links there, once the file drops off of the recently uploaded files list, users won't be able to find your file.

I just modified your post to use the Plain Text input format. The reason that your post was getting cut off is becuase of the < character which is special in HTML (the default input format)

Maple can display a sphere using plottools[sphere]

The first argument is the centre point, the second is the radius of the sphere

> theSphere := plottools[sphere]([0,0,0], 1.5):
plots[display](theSphere);

Maple Plot

>

Maple can also display a cube using the plots[polyhedraplot] command. The first argument is the center point, the second is that we want a hexahedron (cube), and the polyscale defines how much to scale the cube. By default the sides will all be 1 unit long, so a polyscale of 3 will cause the sides to be 3 units long

> theCube := plots[polyhedraplot]([0,0,0],polytype=hexahedron,polyscale=3, transparency = 0.8):
plots[display](theCube);

Maple Plot

>

And you can display the two objects together using the plots[display] command

> plots[display]( [theSphere,theCube] );

Maple Plot

From here, if you look up plots[animate] you should be able to figure out how to create your final animation

I just tried following the examples on Page 248 and had the same problem that you did. I am going to let our Documentation group know about the problem. Thanks for pointing it out. Is there something specific that you are trying to create with Document blocks? Can I help you with that?

Hopefully this does what you are looking for

> restart:

> interface(prettyprint=3):

> printlevel:=1:

> a:=1:b:=-3:c:=2:

> y:=a*x^2+b*x+c:

> z:=factor(y);

Instead of using printf convert z into a string

> zString := convert( z, string );

Maple Equation

>

Now remove the * from the string. Substitute all * characters with a space

> zString := StringTools[Substitute]( zString, "*", " " );

Maple Equation

And then do the printf

> printf( "%s\n", zString );

It looks like your problem is how you used a large number of tab characgters to make your equations line up. This causes your worksheet to be too wide to fit on a piece of paper. Try removing the tabs, and shrinking your image. This should solve the problem. ____ William Spaetzel Marketing Engineer, Maplesoft
