Recent trend in the study of robust control theory the Carathéodory- Fejér-Schur problem of the best approximation of bounded holomorphic functions \(f(z)\) in \(| z| <1\) was indicated a useful tool. This note outlines the basic structure of Carathéodory-Fejér-Schur problem and presents a method for determining the optimal rational function in \(H_ \infty\) that admits a given number of coefficients in its expansion. All the results are already known in the theory of complex function.
