Barycentric−Remez algorithms for best polynomial approximation in the chebfun system

Barycentric−Remez algorithms for best polynomial approximation in the chebfun system

Show other versions (2)

Variants of the Remez algorithm for best polynomial approximation are presented based on two key features: the use of the barycentric interpolation formula to represent the trial polynomials, and the setting of the whole computation in the chebfun system, where the determination of local and global...
