Categories: Mathematics
Type: BOOK - Published: 1981-03-31 - Publisher: Cambridge University Press

Most functions that occur in mathematics cannot be used directly in computer calculations. Instead they are approximated by manageable functions such as polynomials and piecewise polynomials. The general theory of the subject and its application to polynomial approximation are classical, but piecewise polynomials have become far more useful during the
