Abstract
Numerical computation of Fourier series is an important problem of the numerical application theory. In this paper, we present two recursive algorithms for evaluation of the Fourier series,
, wherea i andb i are known complex constants andx is an evaluation point. Compared to some traditional algorithms, the new algorithms take only half of the arithmetic operations.
