lapack_dgesv()

subroutine nwtc_lapack::lapack_gesv::lapack_dgesv	(	integer, intent(in)	N,
		real(r8ki), dimension( :, : ), intent(inout)	A,
		integer, dimension( : ), intent(out)	IPIV,
		real(r8ki), dimension( :, : ), intent(inout)	B,
		integer(intki), intent(out)	ErrStat,
		character(*), intent(out)	ErrMsg
	)

general solve: Computes the solution to system of linear equations A * X = B for GE matrices.

use LAPACK_GESV (nwtc_lapack::lapack_gesv) instead of this specific function.

Parameters

[in]	n	The number of linear equations, i.e., the order of the matrix A. N >= 0.
[in,out]	a	On entry, the N-by-N coefficient matrix A. On exit, the factors L and U from the factorization A = P*L*U; the unit diagonal elements of L are not stored.
[in,out]	b	On entry, the N-by-NRHS matrix of right hand side matrix B. On exit, if INFO = 0, the N-by-NRHS solution matrix X.
[out]	ipiv	The pivot indices that define the permutation matrix P; row i of the matrix was interchanged with row IPIV(i).
[out]	errstat	Error level
[out]	errmsg	Message describing error

lapack_sgesv()

subroutine nwtc_lapack::lapack_gesv::lapack_sgesv	(	integer, intent(in)	N,
		real(siki), dimension( :, : ), intent(inout)	A,
		integer, dimension( : ), intent(out)	IPIV,
		real(siki), dimension( :, : ), intent(inout)	B,
		integer(intki), intent(out)	ErrStat,
		character(*), intent(out)	ErrMsg
	)
