qr-methods: The QR Decomposition of a gpuR matrix
In cdeterman/gpuR: GPU Functions for R Objects

Description Usage Arguments Value Note Author(s) See Also

qr computes the QR decomposition of a gpuR matrix

## S3 method for class 'gpuMatrix'
qr(x, ..., inplace = FALSE)

## S3 method for class 'vclMatrix'
qr(x, ..., inplace = FALSE)

`x`	A gpuR matrix
`...`	further arguments passed to or from other methods
`inplace`	Logical indicating if operations performed inplace

A list containing the QR decomposition of the matrix of class gpuQR. The returned value is a list with the following components:

qr a matrix with the same dimensions as x.
betas vector of numeric values containing additional information of qr for extracting Q and R matrices.

This an S3 generic of qr. The default continues to point to the default base function.

Furthermore, the list returned does not contain the exact same elements as qr. The matrix storage format applied herein doesn't match the base compact form. The method also doesn't return qraux, rank, or pivot but instead returns betas
