CGETF2 computes an LU factorization of a general mbyn matrix A using partial pivoting with row interchanges.
The factorization has the form A = P * L * U where P is a permutation matrix, L is lower triangular with unit diagonal elements (lower trapezoidal if m > n), and U is upper triangular (upper trapezoidal if m < n).
This is the rightlooking Level 2 BLAS version of the algorithm.
[in]  m  INTEGER The number of rows of the matrix A. M >= 0. 
[in]  n  INTEGER The number of columns of the matrix A. N >= 0 and N <= 1024. On CUDA architecture 1.x cards, N <= 512. 
[in,out]  dA  COMPLEX array, dimension (LDDA,N) On entry, the m by n matrix to be factored. On exit, the factors L and U from the factorization A = P*L*U; the unit diagonal elements of L are not stored. 
[in]  ldda  INTEGER The leading dimension of the array A. LDDA >= max(1,M). 
[out]  ipiv  INTEGER array, dimension (min(M,N)) The pivot indices; for 1 <= i <= min(M,N), row i of the matrix was interchanged with row IPIV(i).
