subroutine dqrt05 (integer m, integer n, integer l, integer nb, double precision, dimension(6) result)

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 |
