[PHP] matrix functions
hi list, i have a question regarding a class for matrix modifications so i dont have to re-invent the wheel ;) i would like to do things like this: matrix with 5*5 colums/rows x x x x x 0 0 0 0 0 x x x x x x x x x x x x x x x x x x x x x x x x x 0 0 0 0 0 x x x x x x x x x x maybe that is incredebly stupid and simple but my brain doesnt tell me anything right now - how can i transform colums/rows quickly and efficient? Any help appreciated! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] matrix functions
I think this will work. You'll have to test it to confirm: $A[0][0] = x; $A[0][1] = x; $A[0][2] = x; $A[0][3] = x; $A[0][4] = x; $A[1][0] = 0; $A[1][1] = 0; $A[1][2] = 0; $A[1][3] = 0; $A[1][4] = 0; $B = $C = array(); $B = $A[0]; $C = $A[1]; $A[0] = $C; $A[1] = $B; -Original Message- From: johannes reichardt [mailto:[EMAIL PROTECTED]] Sent: Monday, June 10, 2002 8:32 PM To: [EMAIL PROTECTED] Subject: [PHP] matrix functions hi list, i have a question regarding a class for matrix modifications so i dont have to re-invent the wheel ;) i would like to do things like this: matrix with 5*5 colums/rows x x x x x 0 0 0 0 0 x x x x x x x x x x x x x x x x x x x x x x x x x 0 0 0 0 0 x x x x x x x x x x maybe that is incredebly stupid and simple but my brain doesnt tell me anything right now - how can i transform colums/rows quickly and efficient?

Re: [PHP] matrix functions
If there isn't one, (have you tried phpclasses.org etc.), I think the string functions are powerful enough. What kind of manipulations you need? Is it simple column/row transforms or doing all kinds of maptrix operations? hi list, i have a question regarding a class for matrix modifications so i dont have to re-invent the wheel ;) i would like to do things like this: matrix with 5*5 colums/rows x x x x x 0 0 0 0 0 x x x x x x x x x x x x x x x x x x x x x x x x x 0 0 0 0 0 x x x x x x x x x x maybe that is incredebly stupid and simple but my brain doesnt tell me anything right now - how can i transform colums/rows quickly and efficient?

If all you want to do is move one row of a matrix to another then stuff your matrix into an array and use array_slice(), array_splice(). -- Jason Wong - Gremlins Associates - www.gremlins.com.hk Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * /* Absurdity, n.: A statement or belief manifestly inconsistent with one's own opinion. -- Ambrose Bierce, The Devil's Dictionary */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
