input loop data into a matrix

povault — Thu, 29 Mar 2012 16:49:42 Z

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)

comments should be up-vote-able and listed

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

It should be possible to "vote" for comments in the same way as we can vote for "answers".
The comments should be listed, right there next to Answers:

Extract the argument of a trigonometric function

DarthVid — Mon, 14 Feb 2011 20:56:21 Z

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...

Parenthesis and brackets in Maple

johng23 — Mon, 31 Jan 2011 02:17:13 Z

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...

What is the new MaplePrimes UI trying to indicate?

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...

Small bug with escaping certain characters in comments in Maple 14

ExpHP — Wed, 17 Nov 2010 15:29:29 Z

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.

Possible bugs in Maple 14 (Evalf command and more)

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...

Last Action doesn't capture the latest comments in a thread

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

Badges updating

Alec Mihailovs — Sat, 05 Jun 2010 21:39:28 Z

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.
