t, if JOBQ = 'I', then the leading M-by-M part of
          this array contains the matrix of accumulated orthogonal
          row transformations performed.
          If JOBQ = 'N', the array Q is not referenced and can be
          supplied as a dummy array (i.e. set parameter LDQ = 1 and
          declare this array to be Q(1,1) in the calling program).

  LDQ     INTEGER
          The leading dimension of array Q. If JOBQ = 'U' or
          JOBQ = 'I', LDQ &gt;= MAX(1,M); if JOBQ = 'N', LDQ &gt;= 1.
