I'd like to gauge interest in an online session on authoring Maple documents using new features in Maple 10: document blocks, embedded components, tables, autoexec code, task templates, embedded assessment, 2d math, etc.
Would you participate in such a (free) session?

Similarly to

searching of digits of π, Maple can access other Internet resources. In particular, here is an example of accessing MAGMA through

William Stein's online SAGE/MAGMA/PARI calculator,

Will mentioned

in his blog a problem of finding the first occurence in π the given sequence of digits - a birthday, for example. It can be done in Maple through the search engine at

Hello dear Maple users!
I have the following problem that I am trying to solve with maple.
I have a set of data points (i made these up for now, the real set has more points)
x:=( 1,2,3,4,5,6,7,8 )
y:=( 1,2,3,4,5,6,7,8 )
z:=( 3,1,3,2,4,7,7,9 )
Now, I know how to surface fit this and get maple to formulate an equation
for z=f(x,y) with the following statement:
w:=(Statistics:-Fit(a + b*x + c*y + d*x^2 + e*x*y+f*y^2,

Hi.
There is a command called genvecs in mathcad and i wonder if there is something similar in maple.
Or can somebody tell me how to make the same in maple.
Regards M

has someone a sheet about percolation theory ?
I put a very simple one on my blog:

percolation
Can maple do this ? and how .... I know you can do the graph, but I need to know if maple can do my problem.
ex: Y(t+1) + Y(t) = (-1)^t
and y(0) = 2

Hello,

I am looking for an explanation for the following behavior :

> f := proc(x) somefunc(x) end proc:

> a := table([variable=z]):

> f(a);

somefunc(a)

> f(a) assuming z::real;

somefunc(table([variable=z]))

Why is 'a' replaced with its corresponding table in the second case? And is it possible to use the name 'a' in the return value?

-- Thanks for any reply,

Franky.

Hello!

I´m Trying to do numerical integration for a function defined by a product of characteristic functions. I either receive the message " Error, (in unknown) too many levels of recursion " or "error, (in evalf/int) unable to handle singularity". What should I do?

f_1:=(x,y,z,w)->piecewise(x+w > 0 , 1);

f_2:=(x,y,z,w)->piecewise(x*w - y*z > 0,1);

f_3:=(x,y,z,w)->piecewise((x+w)^2 - 4*(x*w - y*z)<0,1);

prod:=(x,y,z,w)->f_1(x,y,z,w)*f_2(x,y,z,w)*f_3(x,y,z,w);

I want to integrate prod, with all four variables ranging from -1 to 1.

Thank you, Bernardo

Hi, I am trying to call a Matlab function from Maple. The Matlab function requires 33 input variables, but when I call this function with this many variables I get the following error message:
"Error, (in ExecuteCommand) Matlab command string is too long"
My objective is to maximize this function using GlobalSOlve but first I want to just call it. I would appreciate if someone can help me with this.
Cheers

Hi!
I have a two part question:
I am plotting a matrix as multiple graphs: column1 v column2, column1 v column3 etc
I have a worksheet set up so that some of the graphs can be completely equal to 0. I am plotting all the graphs on the one set of axes for comparison, and so the null graphs don't appear. However, I am having problems getting a legend. I only want to display a coloured legend (each plot is a different colour) for each graph that is non zero. How can I do this?
Second part, I have created a text box next to the graph that displays the names of the non zero graphs as strings. Can I make these strings the same colour as their respective graphs?

Hi everyone!
I would like to create a worksheet witb multiple worksheets, and I would like to use sections and subsections. Can anyone please tell me how to lock certain sections/subsections closed so users cannot open then?
Thanks :)

Hi dear members of this Forum,

I want to generate a list which depend on "n";

for n=2 I would like to generate the following list

>[[p1>q1, p2>q2],

>[p1>q1, p2<q2],

>[p1<q1, p2>q2],

>[p1<q1, p2<q2]]

for n = 3 I would like to generate the list:

>[ [p1+p2>q1, p1+p3>q2, p2+p3>q3],

[p1+p2>q1, p1+p3>q2, p2+p3<q3],

[p1+p2>q1, p1+p3<q2, p2+p3>q3],

[p1+p2>q1, p1+p3<q2, p2+p3<q3],

[p1+p2<q1, p1+p3>q2, p2+p3>q3],

[p1+p2<q1, p1+p3>q2, p2+p3<q3],

[p1+p2<q1, p1+p3<q2, p2+p3>q3],

[p1+p2<q1, p1+p3<q2, p2+p3<q3]]

for n=4

[ [p1+p2+p3>q1, p1+p2+p4>q2, p1+p3+p4>q3, p2+p3+p4>q4],..

is it possible to implement a package so that the documentation and the help files will be automatically extracted from the sources?

As a newbie to maple, I was wondering how do I find the maximum of a equation under contraint. i can find some but for this one I can't ... and it's getting to me
f=1000*x+7500*y
under constraint:
g=10000000-(20000*x^0.8)*y^1.2
and for
f=(20000*x^0.8)*y^1.2
under constraint:
g=125000-1000*x-7500*y
Who do I find the maximum using MAple 10 !!!????
