ZCHKRQ

Purpose:

    !>
    !> ZCHKRQ tests ZGERQF, ZUNGRQ and ZUNMRQ.
    !>

Parameters
    DOTYPE

    !>          DOTYPE is LOGICAL array, dimension (NTYPES)
    !>          The matrix types to be used for testing.  Matrices of type j
    !>          (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
    !>          .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
    !>

    NM

    !>          NM is INTEGER
    !>          The number of values of M contained in the vector MVAL.
    !>

    MVAL

    !>          MVAL is INTEGER array, dimension (NM)
    !>          The values of the matrix row dimension M.
    !>

    NN

    !>          NN is INTEGER
    !>          The number of values of N contained in the vector NVAL.
