+/*  ======= */
+
+/*  ZUNGRQ generates an M-by-N complex matrix Q with orthonormal rows, */
+/*  which is defined as the last M rows of a product of K elementary */
+/*  reflectors of order N */
+
+/*        Q  =  H(1)' H(2)' . . . H(k)' */
+
+/*  as returned by ZGERQF. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  M       (input) INTEGER */
+/*          The number of rows of the matrix Q. M >= 0. */
+
+/*  N       (input) INTEGER */
+/*          The number of columns of the matrix Q. N >= M. */
+
+/*  K       (input) INTEGER */
+/*          The number of elementary reflectors whose product defines the */
+/*          matrix Q. M >= K >= 0. */
+
+/*  A       (input/output) COMPLEX*16 array, dimension (LDA,N) */
+/*          On entry, the (m-k+i)-th row must contain the vector which */
+/*          defines the elementary reflector H(i), for i = 1,2,...,k, as */
+/*          returned by ZGERQF in the last k rows of its array argument */
+/*          A. */
+/*          On exit, the M-by-N matrix Q. */
