int PLASMA_dgesv_incpiv_Tile	(	PLASMA_desc *	A,
		PLASMA_desc *	L,
		int *	IPIV,
		PLASMA_desc *	B
	)

PLASMA_dgesv_incpiv_Tile - Solves a system of linear equations using the tile LU factorization. Tile equivalent of PLASMA_dgetrf_incpiv(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.

Parameters

[in,out]	A	On entry, the N-by-N coefficient matrix A. On exit, the tile L and U factors from the factorization (not equivalent to LAPACK).
[in,out]	L	On exit, auxiliary factorization data, related to the tile L factor, necessary to solve the system of equations.
[out]	IPIV	On exit, the pivot indices that define the permutations (not equivalent to LAPACK).
[in,out]	B	On entry, the N-by-NRHS matrix of right hand side matrix B. On exit, if return value = 0, the N-by-NRHS solution matrix X.

Returns

Return values

PLASMA_SUCCESS	successful exit
>0	if i, U(i,i) is exactly zero. The factorization has been completed, but the factor U is exactly singular, so the solution could not be computed.
