Abstract: A novel permutation rational function is proposed first, and the algebraic properties of permutation rational are discussed in detail. The application of this permutation rational function ...

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 ...

Rational functions are fundamental in mathematics, particularly in calculus and algebra, serving as building blocks for more complex mathematical models and analyses. Understanding what constitutes a ...

The impedance of power lines is influenced by geological conditions and skin effect, resulting in frequency-dependent characteristics. In this study, a centralized parameter frequency-dependent line ...
