int PLASMA_zgetrf_Tile ( PLASMA_desc *  A,
PLASMA_desc *  L,
int *  IPIV 
)

PLASMA_zgetrf_Tile - Computes the tile LU factorization of a matrix. Tile equivalent of PLASMA_zgetrf(). 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 M-by-N matrix to be factored. On exit, the tile factors L and U from the factorization.
[out] L On exit, auxiliary factorization data, related to the tile L factor, required by PLASMA_zgetrs to solve the system of equations.
[out] IPIV The pivot indices that define the permutations (not equivalent to LAPACK).
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, and division by zero will occur if it is used to solve a system of equations.
