The evaluation of the conjugate function of a periodic spline on a uniform mesh *


We present an 0( N log N) algorithm for the simultaneous evaluation (at all N points of a uniform mesh) of a function conjugate to a periodic spline. The algorithm is based on the attenuation factor theory and makes use of the FFT. It can be applied to other function classes with known attenuation factors also. For the approximation by functions conjugate… (More)
