....can be easily constructed using only series manipulations. T can be constructed with O(n log 2 n) operations using the series manipulation algorithms of Brent Kung [4] and an FFT for polynomial multiplication. The solution to the system can be obtained via the stable Toeplitz solvers of Trench [14] using (d 2 ) operations, or the fast and stable methods (for positive de nite matrices) 3, 12] which require O(d log 2 d) operations. In summary, each iteration requires O(n log 2 n) oating point operations. 5 NEWTON ITERATION In this section we explore the direct use of Newton s method ....
