  = 'P': use the parameters as encoded in QIND.

  QIND    INTEGER array, dimension (K)
          If COMPQ = 'P', then this array describes the generation
          of the orthogonal factors as follows:
             If QIND(I) &gt; 0, then the array Q(:,:,QIND(I)) is
          modified by the transformations corresponding to the
          i-th orthogonal factor in (1) and (2).
             If QIND(I) &lt; 0, then the array Q(:,:,-QIND(I)) is
          initialized to the identity and modified by the
