PLASMA_zgetrf_nopiv - Computes an LU factorization of a general M-by-N matrix A using the tile LU algorithm without row pivoting. WARNING: Don't use this function if you are not sure your matrix is diagonal dominant.
- Parameters
-
[in] | M | The number of rows of the matrix A. M >= 0. |
[in] | N | The number of columns of the matrix A. N >= 0. |
[in,out] | A | On entry, the M-by-N matrix to be factored. On exit, the tile factors L and U from the factorization. |
[in] | LDA | The leading dimension of the array A. LDA >= max(1,M). |
- Returns
- Return values
-
PLASMA_SUCCESS | successful exit |
<0 | if -i, the i-th argument had an illegal value |
>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. |
