Linear Chebyshev Approximation of Complex-Valued Functions
Linear Chebyshev Approximation of Complex-Valued Functions
This paper is concerned with Chebyshev approximation by linear functions to complex-valued data.The problem is nonlinear, and we present a convergent algorithm for its solution.We also pose a related linear problem which is simple to solve, and which produces approximations which are near-best in the Chebyshev sense within a factor …
