Computing numerically with functions instead of numbers

Symbolic computation with functions of a real variable suffers from combinatorial explosion of memory and computation time. The alternative chebfun system for such computations is described, based on Chebyshev expansions and barycentric interpolation. Mathematics Subject Classification (2000). Primary 41A10; Secondary 68W30. Keywords. Chebfun, Chebyshev series.
