First of, thank you commenters, you have helped me so much in the past!

I am doing a matrix inversion with random numbers and I would like to loop the process, and have each inverstion go into a matrix, such that the matrix will be a bunch of rows ( i number of rows) and three columns (the matrix inversion yeieds three values)

I have remarked on this ever since the launch of the second incarnation of mapleprimes. And I recall others expressing similar feelings.

1. It should be possible to "vote" for comments in the same way as we can vote for "answers".

Regards,

I have a very large equation which has an arctan(x,y). I need to be able to extract the arguments x,y and assign them in some variables.

I have tried the solution given here.

Unfortunately, that solution only works for constants, not equations.

For example, if I use the proc given in there with arctan(10,11) it works. But if I use something like arctan...

Just a question about Maple's formatting.  When I type parenthesis, brackets, or absolute value bars, how do I control what size they are displayed?  I'm typing a bunch of expressions as in-line comments for an assignment, and there are multiple parts with parenthesis within brackets, etc.  On certain lines, ever time I put a space after typing, the size of brackets on a previous line will alternate between large and small.  I can insert spaces into random...

I am returning to Maple after a bit of a dry spell (I'll post about that in another posting) and see that each posting summary seems to be more about avatars and big thumbs than about content. I don't actually care about thumbs up or down; it's content that I want to know about. If 10 people think the post is not helpful, and I think that it is helpful, that's what counts. And it seems to me that the posts might be ordered by thumbs, and I'd like to see date order. Maybe I...

Just a small issue with how you insert a ^ (caret, wedge, circumflex, arrow, hat, what have you), / (forward slash), or * (star, asterisk) as a literal in a comment in Maple.

In regular code, it works fine;

Typing \_ produces _
Typing \^ produces ^
Typing \/ produces /
Typing \* produces *

In a comment, only underscores work as expected.  The caret, asterisk and slash leave behind the escaping backslash, which you will have to go back and delete yourself.

Thank you very much "Preben Alsholm". Your help was very useful for me. I'm very happy now.

Dear Maple users

I use Maple in my physics class in high school. In connection to that I have stumbled on a couple of oddities with the new version 14:

It looks like a bug, that Maple...

Adding a comment to an answer doesn't seem to register it as the last action in a thread.

 

How the badges are updated? Is it done manually?

In particular, I voted many posts up (Thumbs Up), used 2D-math more than 5 times (2-Dimensional), left more than 10 comments (Commenter) etc.

I have an Array A with 90 rows and 16 columns.

The first column of each row denotes the name of a card, while the other 15 colums of each row specify certain characteristics of that card.

Moreover I defined a couple of selection rules Ri, to define sublists of A, which contain only the entries of the first column of A and where the number of elements in Ri is known a priori.

E.g.
R1:=[0$14]:
q:=1:
for i to 90 do
if A[i,2]=4 or A[i,2]=0 then
R1[q]:=A[i,1]:
q:=q+1:
end if:
end do:

I have many Maple T A questions written in LaTeX most of which include \code sections with variables. When I LaTeX the question files I get a pdf which shows all code and the variable names. I can't show the students the resulting pdf file with all the code comments. But I would like to show the students a collection of sample problems. I could print the MapleTA html pages, but I would rather just use the existing latex files to generate sample questions. My goal is to include these question in a book.

I thought that some of you would be interested in Tom Lee's latest blog post at Maplesoft.com regarding MapleSim 4, and what it means to both Tom and Maplesoft.   As always, your comments and thoughts are greatly appreciated.

You can read his post here.

Consider  S=sum((-1)^n*(n^(1/n)-a),n=1..infinity).
S=1/2*(a+2m-1), where m is the MRB constant.

Let m = MRB constant = sum((-1)^n*(n^(1/n)-1),n=1..infinity)
