Subject: QR codes "economy size" decomposition



Hello JAMA users,

I would like to request if anyone has a version of  QRDecomposition that 
does "economy size" decomposition the same as in Matlab command like the 
following:

[Q,R] = QR(A,0) produces the "economy size" decomposition.
If m>n, only the first n columns of Q and the first n rows of R are
computed. If m<=n, this is the same as [Q,R] = QR(A).


Thanks,
sione.
