Abstract: The so-called non-linear vector fitting (NL-VF) technique was recently introduced as a new method for rational function approximation in the frequency domain (FD). While the classical vector ...

rational approximations of π (pi) using Python. Learn how fractions can closely approximate irrational numbers and discover why famous ratios like 22/7 and 355/113 work so well. We’ll use Python to ...

Goethe once compared a string quartet to a conversation among “four rational people,” and the phrase serves as the title for a new documentary about the Emerson String Quartet, one of the most ...

Abstract: The purpose of the article is to take a broader look at classical rational approximation methods in applications to fractional order systems. The fundamental problem is the transformation of ...
