Your post got mangled because you did not escape the angle brackets. These have special meaning in HTML, so they are not displayed. The easiest solution is to click on Input Formats and then choose "Plain Text", this will cause everything you typed to appear exactly as you typed it.

.mwz is a proprietary format created by Maplesoft to protect our electronic books from copying. Creating these files requires a tool that Maplesoft has not released publicly. So, it is not possible for you to create .mwz files. However, I am curious as to why you wish to create .mwz files? If you are creating a product that you would like to sell, you should look into the MapleConnect program. Members of this program would be able to have their files distributed in .mwz.

As you can see on the Maple 11 Professional Page.

Maple 11 Professional version now includes:
  • Maple 11
  • MapleNet
  • Maple Toolbox for MATLAB
  • Elite Maintenance Program
Maple itself is the same, but if you purchase the professional version of Maple, it includes the additional products.

This comment was authored by acer, I reposted it here, moving it from a comment to an unrelated page. Is this the sort of thing that you're after? ft := (n,v) -> Zeta(0,n+1,1-2*Pi*v*I)/Zeta(n+1): mag := (n,v) -> evalf( sqrt(ft(n,v)*conjugate(ft(n,v))) ): fsolve( 'mag'(2,v)=0.5, v=0..0.2 ); fsolve( 'mag'(3,v)=0.5, v=0..0.2 ); fsolve( 'mag'(4,v)=0.5, v=0..0.2 ); The above produced these results, 0.1213463920 0.1006163849 0.08869465478 But that was quite a bit slower than it had to be, because of all the function calls. One could also just use expressions for ft and mag. Ie, restart: > ft := Zeta(0,n+1,1-2*Pi*v*I)/Zeta(n+1): > mag := sqrt(ft*conjugate(ft)): > fsolve( V->evalf(eval(mag,[n=2,v=V]))=0.5, 0..0.2 ); > fsolve( V->evalf(eval(mag,[n=3,v=V]))=0.5, 0..0.2 ); > fsolve( V->evalf(eval(mag,[n=4,v=V]))=0.5, 0..0.2 ); That produced these results. 0.1213463920 + 0. I 0.1006163849 + 0. I 0.08869465476 + 0. I The simplify() routine is one means to get rid of the 0.*I artefacts in those results, after the fact. acer
Maple does not let you assign values to variables that are passed as parameters. If you change your code to
inc := proc(x)
   local output;
   output := x+1;
   return output;
end proc;
It will work fine.

Here is a procedure that will split up a given number into the given length.

> cutNum := proc( number, length := 3)
local strNum, strLen;
strNum := convert( number, string );
strLen := StringTools:-Length( strNum );
ListTools:-Reverse([ seq( parse( StringTools:-SubString(
strNum, max(strLen - ( i +1 )* length,0 )+1..
strLen-i*length )), i=0..floor( strLen / length ) )]);

end proc:

> cutNum( 345273567, 2);

Maple Equation

> cutNum( 632096185, 3 );

It is easy to define a procedure that takes a list, if you don't define the type of the argument, it will take anything. Or you can specifiy a list as below:

> listProc := proc( L::list )
nops ( L );
end proc;

>

Maple Equation

>

As you can see, this proc needs a list:

> listProc(435);

Error, (in listProc) invalid input: listProc expects its 1st argument, L, to be of type list, but received 435

And takes a list just fine

> listProc([4,6,3,4,7]);

As I posted in a reply to your blog entry:

The reason for the Maple Equation statements instead of your Math is beacuse the HTML converter does not support all types of Maple equations. But if you download the worksheet or view the file on MapleNet, you will see all the equations.

I definitely see that this is a problem for people posting worksheets, but at this time I don't see a fix to the problem. I will look into it in the future.

What you saw was probably the Maple Classic Worksheet. If you are using Windows you can open it by clicking on "Classic Worksheet Maple" If you are in Linux/Unix, try the "maple -cw" command. You will see that there are many Maple features missing in the Classic interface, it is provided so that users with computers which are not powerful enough to run the Java interface will still be able to use Maple.

You can give the command a list of points to be used as the center of the plot, so giving a list of points gives you a number of polyhedra

You can use the polyhedrea_supported command to see the different types of polyhedra that are supported

I belive what you are looking for is the time() function. Look up ?time to read about it. I posted earlier a file that demonstrates the use of time(), here it is: View 1_delayPlot.mw on MapleNet or Download 1_delayPlot.mw

It looks like you have found a limitation in Maple. Currently in order to insert text after output, you will have to make sure that you type the text before you create the output.

As far as I know Maple does not have an option to print page numbers automatically. Which version of Maple are you using? Are you in the Standard Interface?. Can you post a screenshot showing the dialog that you are using to enable page numbers?

If you change "statistics" to "Statistics" you should get the plot that you want. Maple is case sensitive, so you have to make sure to use the right captialization for packages and commands.

I haven't tested this in Maple T.A. but as you can see, it works fine in Maple.

> with(Statistics):

> T:=PieChart(["a" = 2, "b" = 2, "c" = 1], color = red .. yellow, explode = [seq(i, i = "a" .. "c")]):
