Item DescriptionThis is the first publication in book form of the author's approximations for digital computers, formerly available only in loose sheets; Part I of the book introduces the collection of useful and illustrative approximations, each of which is presented with a carefully drawn error curve in Part II... undoubtedly _the_ book in the growing field of special function approximations. It is both a necessary reference book for all digital computer centers, and the best book for an introduction to this interesting & difficult field' (from the dj flap, quoted from the Journal of the Association for Computing Machinery.
CONTENTS -- Concerning Best Fit; Linear Weights; An Iterative Procedure; Solution of Equations; Chebyshev Polynomials; Concerning Weights Function with a Peak; Rates of Convergence; Choice of Form; A Scoring-Camera Problem;
PART II - the equations, error curves, etc. - over 70; References.
'This monograph deals with the subject of best approximation in the sense of Chebyshev as applies to the problem of making univariate functional data available to the high-speed digital computing machine' (from the author's Preface'.
