torch_geqrf

Provides functionality to define and train neural networks similar to
'PyTorch' by Paszke et al (2019) <arXiv:1912.01703> but written entirely in R
using the 'libtorch' library. Also supports low-level tensor operations and
'GPU' acceleration.

torch_geqrf function

<dl><dt>self</dt>
<dd>(Tensor) the input matrix</dd></dl>

Arguments

This is a low-level function for calling LAPACK directly. This function
returns a namedtuple (a, tau) as defined in <code>LAPACK documentation for geqrf</code>_ .
You'll generally want to use <code>torch_qr</code> instead.
Computes a QR decomposition of <code>input</code>, but without constructing
\(Q\) and \(R\) as explicit separate matrices.
Rather, this directly calls the underlying LAPACK function <code>?geqrf</code>
which produces a sequence of 'elementary reflectors'.
See <code>LAPACK documentation for geqrf</code>_ for further details.
