To resolve a problem in the context of generalized spline interpolation the first step is to determine the coefficients from the input samples. The operation is a pre-filtering. This paper offers an ...

Signal interpolation is an old problem that could be resolved by filtering techniques. One dedicated filter is used to determine the coefficients from the input samples and another filter is applied ...

D* generates symbolic derivatives which can be thousands of times faster than those generated by Mathematica or automatic differentiation. Functions with densely interconnected expression graphs, ...
