Need help with reduced row echelon form
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.

row echelon form
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, tol=sqrt(.Machine$double.eps),verbose=FALSE,
fractions=FALSE){
## A: coefficient matrix
## tol: tolerance for checking for 0 pivot
## verbose: if TRUE, print intermediate s...

Row-Echelon Form
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...

IPFILTER_DEFAULT_BLOCK & No route to host
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

rref() for R
Has anyone coded a rref() in R/S?
rref() is MatLab's routine for producing a Row-Reduced Echelon Form of a

tinc + OpenSSL
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

tinc with PPP support
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).
Met vriendelijke groet,
Guus Sliepen...

Balanced trees in tinc
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

Restart when convenient
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
