Model-Driven Applications of Fractional Derivatives and Integrals

no code implementations21 Mar 2014 William A. Sethares, Selçuk Ş. Bayın

Fractional order derivatives and integrals (differintegrals) are viewed from a frequency-domain perspective using the formalism of Riesz, providing a computational tool as well as a way to interpret the operations in the frequency domain.
