Geqrf

Usage

torch_geqrf(self)

Arguments

self

(Tensor) the input matrix

geqrf(input, out=NULL) -> (Tensor, Tensor)

This is a low-level function for calling LAPACK directly. This function returns a namedtuple (a, tau) as defined in LAPACK documentation for geqrf_ .

You'll generally want to use torch_qr instead.

Computes a QR decomposition of input, but without constructing \(Q\) and \(R\) as explicit separate matrices.

Rather, this directly calls the underlying LAPACK function ?geqrf which produces a sequence of 'elementary reflectors'.

See LAPACK documentation for geqrf_ for further details.
