  L       (input) DOUBLE PRECISION array, dimension (LDL,*)
          If JOBL = 'N' and JOBB = 'B', the leading N-by-M part of
          this array must contain the cross weighting matrix L.
          If JOBB = 'B' and SCAL = 'G', then L is modified
          internally, but is restored on exit.
          If JOBL = 'Z' or JOBB = 'G', this array is not referenced.
