torch.geqrf
-
torch.geqrf(input, *, out=None) -> (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 and 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.
