Member Function/Subroutine Documentation

lapack_dgetrf()

subroutine nwtc_lapack::lapack_getrf::lapack_dgetrf	(	integer, intent(in)	M,
		integer, intent(in)	N,
		real(r8ki), dimension( :, : ), intent(inout)	A,
		integer, dimension( : ), intent(out)	IPIV,
		integer(intki), intent(out)	ErrStat,
		character(*), intent(out)	ErrMsg
	)

general matrix factorization: Factor matrix into A=PLU.

use LAPACK_GETRF (nwtc_lapack::lapack_getrf) instead of this specific function.

Parameters

[in]	m	The number of rows of the matrix A. M >= 0.
[in]	n	The number of columns of the matrix A. N >= 0.
[in,out]	a	On entry, the M-by-N matrix to be factored. On exit, the factors L and U from the factorization A = P*L*U; the unit diagonal elements of L are not stored.
[out]	ipiv	The pivot indices; for 1 <= i <= min(M,N), row i of the matrix was interchanged with row IPIV(i).
[out]	errstat	Error level
[out]	errmsg	Message describing error

lapack_sgetrf()

subroutine nwtc_lapack::lapack_getrf::lapack_sgetrf	(	integer, intent(in)	M,
		integer, intent(in)	N,
		real(siki), dimension( :, : ), intent(inout)	A,
		integer, dimension( : ), intent(out)	IPIV,
		integer(intki), intent(out)	ErrStat,
		character(*), intent(out)	ErrMsg
	)
