qr computes the QR decomposition of a gpuR matrix
# S3 method for gpuMatrix
qr(x, ..., inplace = FALSE)# S3 method for vclMatrix
qr(x, ..., inplace = FALSE)
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.
A gpuR matrix
further arguments passed to or from other methods
Logical indicating if operations performed inplace
