Fred,
rref.m is included in Joel Robbin's public domain MINIMAT
("MiniMATLAB") which you can find at:
http://archives.math.utk.edu/software/msdos/linear.algebra/minimat/
Here's the README blurb: (Hope this helps. Best regards -jday).
************************************************************
* The program MINIMAT is in the public domain and may be *
* distributed freely and used for any educational purpose. *
* The only restriction placed on its use is that it should *
* not be resold for profit without the permission of its *
* author Joel W. Robbin. *
************************************************************
Here are the files on this disk:
MINIMAT.EXE The MINIMAT program. Run it from DOS.
MINIMAT.HLP An ordinary ascii text file which can be viewed
from MINIMAT using the help command.
MINIMAT.ERR Another ordinary ascii text file explaining
error messages.
READ.ME This file.
MMLOGIN.M A .m batch file written in the MATLAB programming
language which (if present in the default
directory or in a directory named on the command
line which invoked MINIMAT) is executed automatically
when MINIMAT begins.
MMDEMO.M A .m batch file demonstrating some of MINIMAT's
capabilities. (Invoke it by typing mmdemo at
the #> prompt.)
(All the remaining files are .m function files. TYPE them
from MINIMAT to see how to invoke them.)
RREF.M The Reduced Row Echelon Form.
RREFMUL.M RREF and the MULtiplier.
BED.M The Bi-Equivalence Decomposition.
RBASIS. M A BASIS matrix for the Range.
NBASIS.M A BASIS matrix for the Null space
SOLVE.M Ditto. Uses RREF.M instead of BED.M
RANDSOLN.M A RANDom SOLutioN of A*X=0.
NEXT.M The NEXT permutation in lexicographical order.
SIGNUM.M The SIGNUM of a permutation.
PERMINV.M The INVerse of a PERMutation.
ADJ.M The ADJoint matrix.
SOURFRAM.M The SOURiau-FRAMe algorithm for the characteristic polynomial.
COMPAN.M The COMPanion matrix.
INTINV.M A random INTeger matrix with integer INVerse
RANDSUTR.M A RANDom Srictly Upper TRiangular matrix.
