PLASMA_sgetrf_nopiv_Tile - Computes the tile LU factorization of a matrix. Tile equivalent of PLASMA_sgetrf_nopiv(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors.
[in,out] | A | On entry, the M-by-N matrix to be factored. On exit, the tile factors L and U from the factorization. |
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. |
