I apologize to ask this rather simplistic question, but I am very new to this. I can plot a function such as plot(10*x3, x=1..5); BUT what if the range is only specific points such as x=1, 0,07, 8? What is the syntax for this range?

I'm trying to swap rows of a matrix using the LinearAlgebra package not the linalg one. is there a easy way of doing this?

well, i'm using a Evalution Version Maple .i spend one day time to find how can i change Maple to Document Mode but finally failed. May be Evalution Version doesn't have Work Mode and only have Document Mode? :(

I have a list of lists. The number of lists I have is unknown (though always a positive integer) and the number of elements in each list is unknown (though, again, always a positive integer). Some examples: [[2],[3]]; [[4],[4],[5,1]]; [[3,4,1],[2],[2],[6,7]]; I'd like to form a list of all possible sums formed from one element of each list. The lists of sums from the examples above would be [6]; [13,9]; [13,14,11,14,15,12]; The order doesn't matter, and repeated elements don't matter. I can form these lists when I can control the number of lists in the large list and write an explicit nest of for loops. I figure there's got to be a more elegant and powerful way of producing these sums.

Hi I've got 2 functions of a variable T [x(T) and z(T)] and a varying parameter u and i want to plot x(T) and z(T) against each other and show how the curve changes as u varies (hope that makes sense) how can i do that?

(I think this was posted in the wrong section of mapleprimes.) Hi, I have read the manual on saving to a file many times but it never works for me. I am using Maple 10 on a Mac running MacOS 10.4.10. I have copied the example from the manual and run that and it does work so I am quite confused. Here is what I would like to do: I have a worksheet with lots of definitions,equations, lists, etc. and I would like to have these available on another worksheet. I have tried > save nx; # nx is the name of my worksheet then > read nx; Error, unable to read `nx` I have the same problem with trying to save names e.g.

Hello. I'm having a problem graphing the following parametric equations in 3d , together: x=1-2*t y=-t z=3+t and x= 5+3*s-4*t y=7-5*s-5*t z=-2-s+6*t Thanks, excuse-me my English, I’m foreigner

Hallo, I have a function in form f(x(t)), how can i define it in maple and diff it? thanks a lot ex ante.

Hi, Thanks to a few matrix-transformaties, I have elements like ' 1/2*cos(t)-1/2*3^(1/2)*sin(t) ' which also equals cos(t+1/3*pi) (--> thx to: cos(pi/3) = 1/2 and sin(pi/3) = sqrt(3)/2). But I don't find any way to make maple realize that it can be simplified that way. Can he make such simplifications? thx in advance

How do I use newtons method tutor to find the fixed points of a function?

I am trying to figure out what the heck im doing wrong when embedding the if into the loop:

for a from 1 while a<13 do
if(a=1)
then functions[a]:=m||a;
else functions[a]:=(m||a||rref[1,5]*x^(3))+(m||a||rref[2,5]*x^(2))+(m||a||rref[3,5]*x)+(m||a||rref(4,5)); end if
end do;

I get the Error, unterminated loop

Thanks in advance!

Ok, I'm writing a procedure that will return either true or false as to whether a given coordinate (u,v) lies with the plane polygon, made up of n sets of points (xi,yi). I can write the loop code (I think) to check whether u and v are within the intervals; what i cannot do is define the matrix properly that representsteh points. I think it should look like: A:=linalg[det](linalg[Matrix](3,3,[X,Y,1,x[1],y[1],1,x[2],y[2],1])) Obviously this is for a 3x3; I want to replace the x[1], y[1] with i's; however, no matter which way i do this i get an error message saying that i have invalid parameters for a matrix.

My previous blog entry was a real success. Even though my original idea about multi-part MIME has not gotten anywhere, I do now have a concise way to package a maplet with supplemental files in a single package that can be downloaded via the WWW and automatically extracted and executed. Most of the ideas were presented by acer. acer first suggested that I look at the interactive interface to the InstallerBuilder. The idea here was to embed the maplet in a worksheet saved in a help database (hdb). This did work, but was not suitable for actual use due to the overhead of the installer. In the attempt to reduce this overhead, acer then supplied some code that used march and LibraryTools. To test the product of this interaction, download the file at the URL http://www.math.sc.edu/~meade/TEST/SimpleTest.mla.

Hi Maple experts, I have a seemingly simple procedure that is supposed to create random matrices. What surprises me is the fact that it takes more CPU time evertime I call it (even in a fresh session). The procedure is as follows: Feynman_random_rho := proc(N::posint, d::posint:=2)::'Matrix'(complex[8]); # # returns a random N-qudit density matrix where the optional second argument, d, # specifies the dimension of each subsystem. By default, d=2 is assumed so that # an N-qubit density matrix is generated. # The density matrices are uniformly distributed according to the Hilbert-Schmidt

Hello, I'm trying to integrate (for a homework) the Planck radiation formula. But the result (see the Maple10 worksheet below) is so strange (polylog(4,exp...) stuff) that I can't figure out what it means. I tried to compute taylor series at T=0 (because the exercise is to prove that integral is proportional to T^4) but Maple can't do it.
