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
