Quasi-Interpolant Operators and the Solution of Fractional Differential Problems,oblem is approximated by a spline quasi-interpolant operator. This allows us to construct the numerical solution in an easy way. We show through some numerical tests that the proposed method is efficient and accurate.

https://doi.org/10.1007/978-3-663-08476-1rs. We derive an ESPRIT-like algorithm for the generalized recovery method and illustrate, how the method can be simplified if some frequency parameters are known beforehand. Furthermore, we present a modification of Prony’s method for sparse approximation with exponential sums which leads to a non-linear least-squares problem.

GLARE

-Quartic Butterfly-Spline Interpolation on Type-1 Triangulations, is obtained for enough regular functions as well as the optimal order of approximation. We construct such interpolating splines by combining a quasi-interpolating spline with one step of an interpolatory subdivision scheme. Numerical tests confirming the theoretical results are provided.
