Résumé

In this talk we will discuss rational quadrature rules in a general framework. Rather than focusing on theoretical aspects, we will discuss their advantages and disadvantages for practical use compared to classical (polynomial) quadrature rules, and deal with questions like « how to chose the poles” and « when to chose rational quadrature rules over polynomial quadrature rules”. We conclude with presenting some existing algorithms to compute the nodes and weights in certain types of rational quadrature rules.
