+
+/*  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 */
+/*                to avoid the overflow. */
