-* Purpose
-* =======
-*
-* ZUNGQR generates an M-by-N complex matrix Q with orthonormal columns,
-* which is defined as the first N columns of a product of K elementary
-* reflectors of order M
-*
-* Q = H(1) H(2) . . . H(k)
-*
-* as returned by ZGEQRF.
-*
-* 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. M >= N >= 0.
-*
-* K (input) INTEGER
-* The number of elementary reflectors whose product defines the
-* matrix Q. N >= K >= 0.
-*
-* A (input/output) COMPLEX*16 array, dimension (LDA,N)
-* On entry, the i-th column must contain the vector which
-* defines the elementary reflector H(i), for i = 1,2,...,k, as
-* returned by ZGEQRF in the first k columns of its array
-* argument A.
-* On exit, the M-by-N matrix Q.
-*
-* LDA (input) INTEGER
-* The first dimension of the array A. LDA >= max(1,M).
-*
-* TAU (input) COMPLEX*16 array, dimension (K)
-* TAU(i) must contain the scalar factor of the elementary
-* reflector H(i), as returned by ZGEQRF.
-*
-* WORK (workspace/output) COMPLEX*16 array, dimension (MAX(1,LWORK))
-* On exit, if INFO = 0, WORK(1) returns the optimal LWORK.
-*
-* LWORK (input) INTEGER
-* The dimension of the array WORK. LWORK >= max(1,N).
-* For optimum performance LWORK >= N*NB, where NB is the
-* optimal blocksize.
-*
-* 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.
