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).
