Numerical scheme for calculating of the fractional two-power relaxation laws in time-domain of measurements Original Research Article

A numerical approximation of the three-parameter Mittag-Leffler function, useful for description of the non-exponential relaxation laws, is presented. Our approach is based on the Dirichlet average of the two-parameter Mittag-Leffler function for which the numerical approximation is well developed. We provide estimates for accuracy of the computation.
