rationalmatrices collects classes, methods and tools for creating and manipulating rational matrices, i.e. matrices whose entries are rational functions. It provides the fundamentals for the R package ...

Polynomial interpolation to analytic functions can be very accurate, depending on the distribution of the interpolation nodes. However, in equispaced nodes and the like, besides being badly ...

spectral-fit.jl contains the code we used to do spectral fitting, including functions to generate some plots from the manuscript. example-functions.jl contains example functions which the rational ...

In this paper we characterize rational Szegő quadrature formulas associated with Chebyshev weight functions, by giving explicit expressions for the corresponding para-orthogonal rational functions and ...

Abstract: This paper considers the condition when a rational function F(s) may be represented as the function of the argument s + (1/s). If this condition is satisfied then F(s) is the ratio of ...

Abstract: Over the last two decades, much effort has been devoted to accurately measuring Bidirectional Reflectance Distribution Functions (BRDFs) of real-world materials and to use efficiently the ...
