Hello I have a 3x3 matrix (A), which I would have to reduce to Reduced Row echelon form.  Besides, at every iteration k, the elementary row matrix Ek has to be printed and also print the product of sum Ei (i=1 to k) and A. Any ideas how to go about doing this. KS. [[alternative HTML version deleted]]

Hi everyone, I am looking to use R as a MATLAB replacement for linear algebra. I've done a fairly good job for finding replacements for most of the functions I'm interested in, I John Fox wrote a program for implementing the reduced row echelon form of a matrix (by doing the Gauss-Jordan elimination). I modified it a bit: rref <- function(A,

I think one needs an LU decomposition rather than QR. However, I couldn't find anything off the shelf to do an LU, other than learning that determinant() now uses LU instead of QR or SVD, so the code to do it must be in there for those that want it. You'll probably need to divide rows of U by the first entry if you insist on the unique reduced REF. However, I can't see any reason

I was looking for an R-package that would reduce matrices to row-echelon form, but Google was not my friend; any leads? If not, I wonder if the problem could be expressed in terms of constraint satisfaction...

how to produce a Row Reduced Echelon Form for a matrix in R? Aimin Yan

Hi, After the option IPFILTER_DEFAULT_BLOCK is specified at kernel conf on FreeBSD 4.8 stable (cvsup'd with tag RELENG_4_8), the machine cannot be ping'd by others on the same network. In addition, the machine cannot ping itself. ping localhost (or 127.0.0.1) -> no route to host ping itself with its own ip address -> no route to host The freebsd box, with an external pppoe

Sorry for the cross post, but I can't find the original mail I don't know if it was sent to the OpenAFS or the Samba list... I've managed to fix some compilation/build problems when using '--with-afs' to Samba. Something about undefined attributes: ----- s n i p ----- Linking bin/smbd lib/afs.o: In function `afs_createtoken':

Hello, First: I am not subbed to this list. - So any answers should be CC:ed to me. Thank you. I have a freshly installed debian woody linux box. With 2.4.18 with XFS patch. - I have two drives (76G + 40G) that I have used LVM to get a bigger single volume of. It worked perfectly with scp etc. - But now when I installed samba I get timeouts.

Hello, I just want to ask if it has been considered to use OpenSSL for the encryption stuff. I guess they've spent quite some time on the subject and have the cipher routines both debugged and optimized. I know that some of the current cipher code was taken from SSLeay but since OpenSSL is de facto SSLeay successor, it might give tinc more flexibility and allow the user to choose

Hello, How about including support for PPP in tinc (echelon)? This not as an alternative protocol, but as a replacement for the tap device. Most unices have fully functional PPP daemons; if tinc were to be able to communicate with them, those could be used instead of tap devices (which are only known to Linux natively).

Hi everybody, I'm looking into replacing the linked lists in tinc with balanced trees. Using balanced trees will greatly improve performance for medium to large VPNs. As I see it, there are several options: 1) Use tsearch()/twalk()/etc functions from glibc. + It is in a very standard library - It relies solely on callback functions, which sometimes results in ugly, awkward code (I

So good luck to you all, i will still remain here, i just will not be very Public anymore, it seems i may be upsetting the higher echelons of fBsd, i can see my firewall ya know ;). And i dislike what I see, when all i really did, was report a problem I had myself, and someone I know still has. I am here to only have that addresses, watching the rest of this list function has shown me how weak your security is. Yea sure you might have...

I've moved 1 of our facilities over from 1.2 to 1.4 two weeks back. So far, the only issue that I've encounted is. I have a scheduled CRON job that runs at 3am every Sunday, that issues a: asterisk -rx 'restart when convenient' The first Sunday that it ran, Asterisk never restarted. The CRON logs show that it issued the command successfully. This Sunday, it ran but never
