x, y |
numeric distributed matrices for |
tol |
logical value, determines whether or not columns are zero centered. |
complete |
logical expression of length 1. Indicates whether an arbitrary orthogonal completion of the Q or X matrices is to be made, or whether the R matrix is to be completed by binding zero-value rows beneath the square upper triangle. |
Dvec |
Not implemented for objects of class |
qr.Q()
recovers Q from the output of qr()
.
qr.R()
recovers R from the output of qr()
.
qr.qy()
multiplies y
by Q.
qr.qty()
multiplies y
by the transpose of Q.
