-* Purpose
-* =======
-*
-* ZGETF2 computes an LU factorization of a general m-by-n 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 right-looking Level 2 BLAS version of the algorithm.
-*
-* Arguments
-* =========
-*
-* M (input) INTEGER
-* The number of rows of the matrix A. M >= 0.
-*
-* N (input) INTEGER
-* The number of columns of the matrix A. N >= 0.
-*
-* A (input/output) COMPLEX*16 array, dimension (LDA,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.
-*
-* LDA (input) INTEGER
-* The leading dimension of the array A. LDA >= max(1,M).
-*
-* IPIV (output) 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).
-*
-* INFO (output) INTEGER
-* = 0: successful exit
-* < 0: if INFO = -k, the k-th argument had an illegal value
-* > 0: if INFO = k, U(k,k) 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.
