[edit] A belated apology

I was re-reading our discussion over on Xcode's talk page and I wanted to apologize, because I think I came across rudely. It wasn't my intent at all. I was just trying to be direct and save me typing time and you reading time. I'll try to do better in the future. -- Steven Fisher 16:41, 9 September 2006 (UTC)

No problem, it's forgotten. Good work on the Xcode article. Feel free to edit out what you want from our discussion. --Engelec 21:24, 10 September 2006 (UTC)

[edit] MATLAB's SUM

I noticed your comment on MATLAB's SUM command. I think what you describe is accurate. This is an example of MATLAB trying to do what it thinks you want, which can lead to bugs. I want to be sure you know that SUM takes a second argument, the dimension you want to operate over, and this fixes the problem. --Matthew Simoneau 16:13, 12 October 2006 (UTC)

Yes, you're right. But there are functions where it isn't possible; for instance plot has no dim argument. Function norm has a different, but related problem: it would be useful for computing the norm of each row or column of an array, but norm is defined as the induced norm for matrices.

I've updated the MATLAB article to mention this. Engelec 00:02, 13 October 2006 (UTC)

[edit] SCILAB

Hi. I downloaded Scilab and I'm quite confused. Could you help me out and tell me the proper syntax to solve a simple equation such as "5 + x = 8"? —Preceding unsigned comment added by CorrectInfo (talk • contribs) 14:01, 1 May 2008 (UTC)

I'm not an expert in Scilab, but I guess "8 - 5" or "(8 - 5)/1" should work. Scilab performs numerical computation, so it cannot directly manipulate implicit equations, contrary to Maple. Scilab newsgroup might be helpful. Engelec (talk) 08:22, 2 May 2008 (UTC)
Thank you for your answer. I will try Maple. With regards, —Preceding unsigned comment added by CorrectInfo (talk • contribs) 08:30, 4 May 2008 (UTC)
