Hi everyone,

While I am getting more and more comfortable with the document mode, I have some questions regarding the document block feature:

- What is a document block good for anyway?
- Why not have the whole document in one block?
- Can one join two document blocks?
- when do I "remove the document block"
- How can I make sure that say an informational 2-D math expression inside a document block never gets executed?
-- Can I still...

Hello!  I am writing a Grassmann multiplication operator:

define('`&*`', 'multilinear', 'flat', 'identity' = 1)

So that it automatically constructs operators like &*(arg1, arg2,arg3 ...)

Now I want to teach Maple how to transforms &* with ARBITRARY number of arguments.

How to create a pattern for that?  (to be added to "define")

Can anyone explain these results?  I m trying to check on a more complicated form of this expression, but cannot proceed without understanding what is occurring in this case.

Does anyone know if you can schedual a task in maple ie at 12:00 add a number
to a matrix in a worksheet (Just an simple example to see if it is working)

In windows you can use the "Task Scheduler" to automate stuff that you need to repeat.

Also I dont want the actuall Maple software to actually launch at 12:00, I want everything to happend
in the background.

If you put the maple commands in the "start up code region" of the worksheet I guess it

what should i do to get display buttons in maplet as an input in TextField? so that everytime i click on a button in maplet, the value of that button will show up in TextField as an input, such as if i click on a  Button("1") , the number 1 will show up in the TextField. thanks in advance.

i am solving for a system of df eq's, but the eq's have these little tricky integrals inside them.....so it either retards operation or no solutoin can be found...They look like...

B_12:=(10*a_2*a_3)*(u/( ((10^2+u)^(3/2)) * ((a_2^2+u)^(3/2)) * ((a_3^2+u)) )):

B_122:=(10*a_2*a_3)*(u/( ((10^2+u)^(3/2)) * ((a_2^2+u)^(5/2)) * ((a_3^2+u)) )):

B_123:=(10*a_2*a_3)*(u/( ((10^2+u)^(3/2)) * ((a_2^2+u)^(3/2)) * ((a_3^2+u)^(3/2)) )):

B_23:=(10*a_2*a_3...

My problem looks as follows................pts1FIXED comes from dsolved solution......it plots a empty figure...and i checked that l(the data pairs looks fine)..

--------------------------------------

Energy:=array(1..450);

Time:=array(1..450);

for i from 1 to 450 do 

	

	Energy[i]:=-1*((32*G*Inertia^2*e^2)/(5*c^2))*pts1FIXED(i);

end do:

l := [[t,Energy[t]] $t=1..450]:

plot(l,style=point,symbol=circle,color=blue);

I need some help...i need a solver using the Runge-Kutta method adaptive size control, to solve a sytem of 5 diff eq's, all of them are interlinked...

And 

Say that dsolve numeric produces a results, called Solution, Now ex  solution(0)=1, and in general solution(t) can be evaluated, now, i want to use this, in E(t)=2*solution(t), in a plot, thus...

plot(E(t),t=0..100,....), but returns the error....

hello everyone, this is my first time visit mapleprimes, i just started to use maplets programming, so there are a lot of things i still don't know about this maplet, if i ask some stupid questions please be patient with me.

so i've been trying to write a maplet that will calculate some simple functions such as addition, multiplication, division,...,it's kind of like a calculator. 

i've been trying all day, and no luck so far. help please. 

if i want to create a table which contain buttons label from 0-9 so when i calculate n! i can use the number buttons on the table? please help. 

i found this program in mapleprimes 

Hi,

I have a simulation file consisting of a number of modelica custom componets and maple custom components. I initially generated Random Data with mean 1 and standard deviation 0.5. Constructed all the blocks and combined with a multibody system, it worked fine. However, when I generated Random data with zero mean, then I have this error/problem "Simulation Problem: maximum number of event iterations reached (100) at 1.85000".

I used a couple of pre() function with clock=sample(0,0.01...

What do these parameters of Clutch mean,phi_nominal,w_small,k_locked?

And, how can I use them?

Anyone can tell me the detail?

Thank you.

Hi all.

I want to make a graphical application for a webpage, showing curves with a certain number of points on X axis (about 10 or 15), and some sort of “handles” on curve values (for every curve,...
