Description
Contains the results of a QR decomposition from using the qr() method on a gmatrix object. Note that the gmatrix solve function uses QR decompostion. Also, qr.coef can act on the gqr object. The qr method does not use pivoting or check the matrix rank. The QR and related methods are only available for cuda v7.0 or greater.
Objects from the Class
Objects can be created by calls of the qr() method.Slots
qr:- Information about the Q and R matrices stored as and bject of class
"gmatrix". qraux:- Information about the Q matrix stored as an object of class
"gvector".
Methods
- qr.coef
- Simular to the
qr.coef function. - solve
- Simular to the
solve.qr function.
Examples
M=gmatrix(grnorm(25), 5,5,dup=FALSE)
y=grnorm(5)
solve(M)
solve(M,y)
myqr =qr(M)
solve(myqr,y)
