              'TS' for testing tall skinny QR
                   and anything else for testing short wide LQ

    M

              M is INTEGER
              Number of rows in test matrix.

    N

              N is INTEGER

              Results of each of the six tests below.
              RESULT(1) = | A - Q R | or | A - L Q |
              RESULT(2) = | I - Q^H Q | or | I - Q Q^H |
              RESULT(3) = | Q C - Q C |
              RESULT(4) = | Q^H C - Q^H C |
              RESULT(5) = | C Q - C Q |
