SphericalHankelH2[n, z] gives the spherical Hankel function of the second kind h_n^(2)(z).

TrigToExp[expr] converts trigonometric functions in expr to exponentials.

Extrapolation methods are a class of arbitrary-order methods with automatic order and step-size control. The error estimate comes from computing a solution over an interval ...

GraphSum[g_1, g_2, ...] constructs the graph resulting from joining the edge lists of graphs g_1, g_2, and so forth.

IdenticalQ[g, h] yields True if graphs g and h have identical edge lists, even though the associated graphics information need not be the same.

ReadGraph[f] reads a graph represented as edge lists from file f and returns a graph object.

RGFs[n] lists all restricted growth functions on the first n natural numbers in lexicographic order.

StableMarriage[mpref, fpref] finds the male optimal stable marriage defined by lists of permutations describing male and female preferences.

StronglyConnectedComponents[g] gives the strongly connected components of directed graph g as lists of vertices.
