Abstract: A recent theme in algorithms and software is efficient numerical computation with functions in a manner that "feels symbolic" since the accuracy is high and underlying discretizations (Chebyshev, Fourier,...) are hidden from the user. Projects of this kind include Chebfun, pychebfun, ApproxFun, and PaCAL. A pervasive theme in this work is the use of continuous analogues of familiar discrete mathematical objects and algorithms. This minisymposium will
present new developments in the areas of (1) differential and integral equations, (2) working with functions, and (3) rootfinding and linear algebra.
