+
+/*  Purpose */
+/*  ======= */
+
+/*  CGELSY computes the minimum-norm solution to a complex linear least */
+/*  squares problem: */
+/*      minimize || A * X - B || */
+/*  using a complete orthogonal factorization of A.  A is an M-by-N */
+/*  matrix which may be rank-deficient. */
+
+/*  Several right hand side vectors b and solution vectors x can be */
+/*  handled in a single call; they are stored as the columns of the */
+/*  M-by-NRHS right hand side matrix B and the N-by-NRHS solution */
+/*  matrix X. */
+
+/*  The routine first computes a QR factorization with column pivoting: */
+/*      A * P = Q * [ R11 R12 ] */
+/*                  [  0  R22 ] */
+/*  with R11 defined as the largest leading submatrix whose estimated */
+/*  condition number is less than 1/RCOND.  The order of R11, RANK, */
+/*  is the effective rank of A. */
+
+/*  Then, R22 is considered to be negligible, and R12 is annihilated */
+/*  by unitary transformations from the right, arriving at the */
+/*  complete orthogonal factorization: */
+/*     A * P = Q * [ T11 0 ] * Z */
+/*                 [  0  0 ] */
+/*  The minimum-norm solution is then */
+/*     X = P * Z' [ inv(T11)*Q1'*B ] */
+/*                [        0       ] */
+/*  where Q1 consists of the first RANK columns of Q. */
+
+/*  This routine is basically identical to the original xGELSX except */
+/*  three differences: */
+/*    o The permutation of matrix B (the right hand side) is faster and */
+/*      more simple. */
+/*    o The call to the subroutine xGEQPF has been substituted by the */
+/*      the call to the subroutine xGEQP3. This subroutine is a Blas-3 */
+/*      version of the QR factorization with column pivoting. */
+/*    o Matrix B (the right hand side) is updated with Blas-3. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  M       (input) INTEGER */
+/*          The number of rows of the matrix A.  M >= 0. */

+/*          The number of right hand sides, i.e., the number of */
+/*          columns of matrices B and X. NRHS >= 0. */
+
+/*  A       (input/output) COMPLEX array, dimension (LDA,N) */
+/*          On entry, the M-by-N matrix A. */
+/*          On exit, A has been overwritten by details of its */
+/*          complete orthogonal factorization. */
+
+/*  LDA     (input) INTEGER */
+/*          The leading dimension of the array A.  LDA >= max(1,M). */
+

+/*  JPVT    (input/output) INTEGER array, dimension (N) */
+/*          On entry, if JPVT(i) .ne. 0, the i-th column of A is permuted */
+/*          to the front of AP, otherwise column i is a free column. */
+/*          On exit, if JPVT(i) = k, then the i-th column of A*P */
+/*          was the k-th column of A. */
+
+/*  RCOND   (input) REAL */
+/*          RCOND is used to determine the effective rank of A, which */
+/*          is defined as the order of the largest leading triangular */
+/*          submatrix R11 in the QR factorization with pivoting of A, */
+/*          whose estimated condition number < 1/RCOND. */
+
+/*  RANK    (output) INTEGER */
+/*          The effective rank of A, i.e., the order of the submatrix */
+/*          R11.  This is the same as the order of the submatrix T11 */
+/*          in the complete orthogonal factorization of A. */
+
+/*  WORK    (workspace/output) COMPLEX array, dimension (MAX(1,LWORK)) */
+/*          On exit, if INFO = 0, WORK(1) returns the optimal LWORK. */
+

+/*          where NB is an upper bound on the blocksize returned */
+/*          by ILAENV for the routines CGEQP3, CTZRZF, CTZRQF, CUNMQR, */
+/*          and CUNMRZ. */
+
+/*          If LWORK = -1, then a workspace query is assumed; the routine */
+/*          only calculates the optimal size of the WORK array, returns */
+/*          this value as the first entry of the WORK array, and no error */
+/*          message related to LWORK is issued by XERBLA. */
