Function Documentation

geqrf()

template<BlasArray< 3 > A, BlasArrayFor< A, 2 > TAU, BlasArrayFor< A, 1 > W = vector_value_t<A>>
requires (has_F_layout<A, TAU>)

int nda::lapack::geqrf	(	A &&	a,
		TAU &&	tau,
		W &&	work = vector_value_t<A>{} )

Generic-friendly overload of nda::lapack::geqrf for batches stored as 3-dimensional arrays.

It simply calls nda::lapack::geqrf_batch and lets generic code call geqrf(...) regardless of whether the input is a single matrix (rank 2) or a batch (rank 3).
