bbtoeplitz  Create a black-box operator for a Toeplitz matrix
   This function returns a black-box operator for a Toeplitz system:
     BB=bbtoeplitz(C,R)
     BB=bbtoeplitz(R)

   where C and R are the first column and row of the matrix. If only
   the first row is given, the system will be Hermitian.
   The first element of R and C must be identical.

   The matrix can be formed explicitly as A=toeplitz(C,R).
