  TYPET   CHARACTER*1
          Specifies the type of T, as follows:
          = 'R':  T contains the first block row of an s.p.d. block
                  Toeplitz matrix; the ICC factor R is upper
                  trapezoidal;
          = 'C':  T contains the first block column of an s.p.d.
                  block Toeplitz matrix; the ICC factor R is lower
                  trapezoidal; this choice leads to better
                  localized memory references and hence a faster
