R help - Oct 2009 - 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.

Can you convince us that this isn't a homework problem (e.g. tell us what
your
application/context is)?

Dear KS,

Some time ago, I posted a solution to this problem (minus the ERO matrices)
to the r-help list. You'll find the relevant functions at
<http://socserv.socsci.mcmaster.ca/jfox/Courses/R-programming/matrixDemos.R>
.

Regards,
 John
