void container::kernels::lapack_geqrf_inplace< T, Device >::operator()	(	const int	m,
		const int	n,
		T *	A,
		const int	lda
	)

Perform in-place QR factorization of a matrix using LAPACK's geqrf function.

This function computes the QR factorization of an m-by-n matrix A as A = Q * R, where Q is an orthogonal/unitary matrix and R is an upper triangular matrix. The factorization is performed in-place, meaning the input matrix A will be modified.

On exit: A is overwritten with the QR factorization Q orthogonal/unitary matrix

Parameters

m	The number of rows in the matrix A. m >= 0
n	The number of columns in the matrix A. n >= 0
A	Pointer to the matrix A to be factorized. On exit, contains the QR factorization
lda	The leading dimension of the matrix A. lda >= max(1, m)
