Rational approximating functions are frequently selected for this purpose. This thesis is a survey of several methods that have been proposed for obtaining best rational Chebyshev approximations to functions defined on finite point sets. Most of the methods formulate the problem as a mathematical programming problem. Numerical examples are given to compare the efficiency of the methods.87 pagesAvailable to the World Wide WebThesis
