PLASMA - Parallel Linear Algebra for Scalable Multi-core Architectures
int PLASMA_cgetrf_Tile ( PLASMA_desc A,
int *  IPIV 
)

PLASMA_cgetrf_Tile - Computes the tile LU factorization of a matrix. Tile equivalent of PLASMA_cgetrf(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.

Parameters
[in,out]AOn entry, the M-by-N matrix to be factored. On exit, the tile factors L and U from the factorization.
[out]IPIVThe pivot indices that define the permutations (not equivalent to LAPACK).
Returns
Return values
PLASMA_SUCCESSsuccessful exit
>0if 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.
