This is a Windows specific question. If I currently have the worksheet named "myworksheet.mw" in the directory "C:\projects" open in Maple, is there a command I can execute to retreive the path "C:/projects" as a string? 

assume f:= x^2*y^3/z^7

would like to get [x^2, y^3, z^(-7)]

compute the squarefree decomposition of the following polynomials in Q[x] and inF_3[x].
(1)  f=x^6-x^5-4x^4+2x^3+5x^2-x-2
(2)  g=x^6-5x^5+12x^4-6x^3-9x^2+12x-4
            

I am trying to solve a fixed-point equation.

However, no solutions are returned, and I get the warning message "Warning, solutions may have been lost."  How can I be sure that the full set of solutions has been returned?  (I should also say that, based on other cases of the same problem, I expect that there are two or three solutions.)

I received an unexpected error message when trying to minimize a function: evaluating

returns the error message

Error, (in @) too many levels of recursion

Why am I getting this message?  It's hard for me to see how minimizing a function involves recursion, unless Maple is trying to iteratively approximate a solution.

I'm attempting to plot several solutions of this differential equation (I have uploaded my worksheet). I have used this series of commands before without issue, but for some reason I keep getting the error message: "Error, (in plot) incorrect first argument" ect.. Does anyone have any insight into what might be going wrong? Thank you.

Respected sir,

     Maple package is very useful to all the Mathematics students to work with. however, i came to know how to solve

system coupled non-linear ODEs with boundary condtions in Maple 12.0. But my doubt is, the tool 'Boundary value problem solver' which methods and submethods are used to solve those BVPs. Sir please, clear my doubt. your response is highly helpfull for me. Please kindly do the need full.

Thanking you.

of 1/(x^(2*sin(x)^2)+x^(2*cos(x)^2)) over the interval 1..infinity? Is it possible to find that with Maple?

How to open batch maple output as mws in Maple Player?  I was used to doing this daily at work before retirement in my university office on a campus computer.  There was an "open" command in a file menu of some sort that I could click on, I seem to remember.   Am just fresh afte downloading Maple Player on my iMac and have it installed.  The file from my batch Maple output is form a run of batch Maple on the office machine that I can logon to remotely from home, as I did in this case.  I get rough looking graphic output (using the alphabet style graphics methods).  It would be good to have a more detailed and fine grained graphics to answer some basic questions that I am analyzing.  Thanks . . !!

Hello, everyone. I have some problem with multithreaded calculation. I just need calculate eigenvalues of matrix m at various parameters (and then export to a file) using advantages of the parallelizing. The following code works but in serial way

restart: with(LinearAlgebra):

m:=ImportMatrix(cat(currentdir(),"m.txt")): # here is matrix m.txt

step:=1:

prc:=proc(k1,k2)

local u,i,j,nmc:

u:=Matrix(ceil(1+(k2-k1)/step),5):

u[1,1]:=k1:

for i from 2 to op([1,1],u) do

u[i,1]:=u[i-1,1]+step:

end do:

for i from 1 to op([1,1],u) do

nmc:=sort(Eigenvalues(m*u[i,1], output='list')):

for j from 2 to op([1,2],u) do

u[i,j]:=nmc[j-1]:

end do:

writedata[APPEND](cat(currentdir(),"u_",convert(k2,string),".txt"), [convert(Re(u[i]),list)]):

print(u[i,1]);

end do:

return finished:

end proc:

with(Threads[Task]):

Start(ArrayTools[Concatenate], 2, Task=[prc,1,20], Task=[prc,20+step,40]);

quit:

The Start(ArrayTools[Concatenate], 2, Task=[prc,1,20], Task=[prc,20+step,40]) function makes two tasks of calculation at the parameter ranges of 1-20 and 21-40. But in this case Start spends twice more time than simply prc(20+step,40). How to realize a multithreaded calculation?

By the way I don't need to use a Concatenate function in Start but without any procedure Start doesn't work.

Hello;
        i am wording on fluid dynamics, in which i can up a system of nonlinear partial differential equation with i am suppose to solve using implicit keller box method. i need an asistance on how to implement this in maple.

error module is maple.dll_unloaded

i have already called stopmaple(kv);

in

testfunction(string hello){....stopmaple(kv));

testfunction(1);

testfunction(2);

when call testfunction again , it got error

Maple people:

The title is the question.  I would like to know if there is any Maple code available, either part of Maple itself or written by a user, to do computations with quaternions or dual quaternions.

I could Google this and probably find something, but I'll probably find a more helpful and less outdated answer here.

I am teaching a student about the subject and I'd like something to help me teach and help him learn.

I have a lot of experience with Maple but I am not a "computer person", so if the code involves fancy "libraries" or something beyond regular Maple worksheets, I may need a few tips how to use it.
