## 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)
