-*  Purpose
-*  =======
-*
-*  DGERQF computes an RQ factorization of a real M-by-N matrix A:
-*  A = R * Q.
-*
-*  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.
-*
-*  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
-*          On entry, the M-by-N matrix A.
-*          On exit,
-*          if m <= n, the upper triangle of the subarray
-*          A(1:m,n-m+1:n) contains the M-by-M upper triangular matrix R;
-*          if m >= n, the elements on and above the (m-n)-th subdiagonal
-*          contain the M-by-N upper trapezoidal matrix R;
-*          the remaining elements, with the array TAU, represent the
-*          orthogonal matrix Q as a product of min(m,n) elementary
-*          reflectors (see Further Details).
-*
-*  LDA     (input) INTEGER
-*          The leading dimension of the array A.  LDA >= max(1,M).
-*
-*  TAU     (output) DOUBLE PRECISION array, dimension (min(M,N))
-*          The scalar factors of the elementary reflectors (see Further
-*          Details).
-*
-*  WORK    (workspace/output) DOUBLE PRECISION 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,M).
-*          For optimum performance LWORK >= M*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.

-*
-*  Further Details
-*  ===============
-*
-*  The matrix Q is represented as a product of elementary reflectors
-*
-*     Q = H(1) H(2) . . . H(k), where k = min(m,n).
-*
-*  Each H(i) has the form
-*
-*     H(i) = I - tau * v * v**T
-*
-*  where tau is a real scalar, and v is a real vector with
-*  v(n-k+i+1:n) = 0 and v(n-k+i) = 1; v(1:n-k+i-1) is stored on exit in
-*  A(m-k+i,1:n-k+i-1), and tau in TAU(i).
