+/*  Purpose */
+/*  ======= */
+
+/*  ZLAQPS computes a step of QR factorization with column pivoting */
+/*  of a complex M-by-N matrix A by using Blas-3.  It tries to factorize */
+/*  NB columns from A starting from the row OFFSET+1, and updates all */
+/*  of the matrix with Blas-3 xGEMM. */
+
+/*  In some cases, due to catastrophic cancellations, it cannot */
+/*  factorize NB columns.  Hence, the actual number of factorized */
+/*  columns is returned in KB. */
+
+/*  Block A(1:OFFSET,1:N) is accordingly pivoted, but not factorized. */
+
+/*  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 */
+
+/*  OFFSET  (input) INTEGER */
+/*          The number of rows of A that have been factorized in */
+/*          previous steps. */
+
+/*  NB      (input) INTEGER */
+/*          The number of columns to factorize. */
+
+/*  KB      (output) INTEGER */
+/*          The number of columns actually factorized. */
+
+/*  A       (input/output) COMPLEX*16 array, dimension (LDA,N) */
+/*          On entry, the M-by-N matrix A. */
+/*          On exit, block A(OFFSET+1:M,1:KB) is the triangular */
+/*          factor obtained and block A(1:OFFSET,1:N) has been */
+/*          accordingly pivoted, but no factorized. */
+/*          The rest of the matrix, block A(OFFSET+1:M,KB+1:N) has */
+/*          been updated. */
+
+/*  LDA     (input) INTEGER */
+/*          The leading dimension of the array A. LDA >= max(1,M). */
+

+/*          JPVT(I) = K <==> Column K of the full matrix A has been */
+/*          permuted into position I in AP. */
+
+/*  TAU     (output) COMPLEX*16 array, dimension (KB) */
+/*          The scalar factors of the elementary reflectors. */

+/*  VN1     (input/output) DOUBLE PRECISION array, dimension (N) */
