          On exit, if COMPQ = 'P', only parts of the leading
          N-by-N-by-K part contain some modified orthogonal factors
          as described by the parameters QIND.
          This array is not referenced if COMPQ = 'N'.

  LDQ1    INTEGER
          The first leading dimension of the array Q.  LDQ1 &gt;= 1,

  LDQ2    INTEGER
          The second leading dimension of the
