DQRT05

Purpose:

    !>
    !> DQRT05 tests DTPQRT and DTPMQRT.
    !>

Parameters
    M

    !>          M is INTEGER
    !>          Number of rows in lower part of the test matrix.
    !>

    N

    !>          N is INTEGER
    !>          Number of columns in test matrix.
    !>

    L

    !>          L is INTEGER
    !>          The number of rows of the upper trapezoidal part the
    !>          lower test matrix.  0 <= L <= M.
    !>

    NB

    !>          NB is INTEGER
    !>          Block size of test matrix.  NB <= N.
    !>

    RESULT

    !>          RESULT is DOUBLE PRECISION array, dimension (6)
    !>          Results of each of the six tests below.
    !>
    !>          RESULT(1) = | A - Q R |
    !>          RESULT(2) = | I - Q^H Q |
    !>          RESULT(3) = | Q C - Q C |
    !>          RESULT(4) = | Q^H C - Q^H C |
    !>          RESULT(5) = | C Q - C Q |
    !>          RESULT(6) = | C Q^H - C Q^H |
