  PLASMA_sgetrf - Computes an LU factorization of a general M-by-N matrix A using the tile LU algorithm with partial tile pivoting with row interchanges. 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).
  [out] | IPIV | The pivot indices that define the permutations.
  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.
