Function/Subroutine Documentation
   subroutine ztsqr01 (character tssw, integer m, integer n, integer mb,
       integer nb, double precision, dimension(6) result)
       ZTSQR01

       Purpose:


            ZTSQR01 tests ZGEQR , ZGELQ, ZGEMLQ and ZGEMQR.

       Parameters
           TSSW

                     TSSW is CHARACTER
                     '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
                     Number of columns in test matrix.

           MB

                     MB is INTEGER
                     Number of row in row block in test matrix.

           NB

                     NB is INTEGER
                     Number of columns in column block test matrix.

           RESULT

                     RESULT is DOUBLE PRECISION array, dimension (6)
                     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 |
                     RESULT(6) = | C Q^H - C Q^H |
