where Q is a complex unitary matrix defined as the product of k elementary reflectors
Q = H(k) . . . H(2) H(1)
as returned by CGEQLF. Q is of order M if SIDE = 'L' and of order N if SIDE = 'R'.
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.
