-* Purpose
-* =======
-*
-* ZGETC2 computes an LU factorization, using complete pivoting, of the
-* n-by-n matrix A. The factorization has the form A = P * L * U * Q,
-* where P and Q are permutation matrices, L is lower triangular with
-* unit diagonal elements and U is upper triangular.
-*
-* This is a level 1 BLAS version of the algorithm.
-*
-* Arguments
-* =========
-*
-* N (input) INTEGER
-* The order of the matrix A. N >= 0.
-*
-* A (input/output) COMPLEX*16 array, dimension (LDA, N)
-* On entry, the n-by-n matrix to be factored.
-* On exit, the factors L and U from the factorization
-* A = P*L*U*Q; the unit diagonal elements of L are not stored.
-* If U(k, k) appears to be less than SMIN, U(k, k) is given the
-* value of SMIN, giving a nonsingular perturbed system.
-*
-* LDA (input) INTEGER
-* The leading dimension of the array A. LDA >= max(1, N).
-*
-* IPIV (output) INTEGER array, dimension (N).
-* The pivot indices; for 1 <= i <= N, row i of the
-* matrix has been interchanged with row IPIV(i).
-*
-* JPIV (output) INTEGER array, dimension (N).
-* The pivot indices; for 1 <= j <= N, column j of the
-* matrix has been interchanged with column JPIV(j).
-*
-* INFO (output) INTEGER
-* = 0: successful exit
-* > 0: if INFO = k, U(k, k) is likely to produce overflow if
-* one tries to solve for x in Ax = b. So U is perturbed
