LogPlot, ListLogPlot, and related functions have been added to the built-in Mathematica kernel. PolarPlot and ListPolarPlot have been added to the built-in Mathematica ...
NonlinearRegress functionality is now available using the built-in function NonlinearModelFit.
ErrorListPlot[{{y_1, dy_1}, {y_2, dy_2}, ...}] plots points corresponding to a list of values y_1, y_2, ..., with corresponding error bars. The errors have magnitudes dy_1, ...
MiniMaxApproximation[expr, {x, {x_0, x_1}, m, n}] finds the rational polynomial function of x, with numerator order m and denominator order n, that gives a mini-max ...
LinkRanks[g] gives the link ranks of the directed graph g as a rule list.
StrongComponents[g] gives a list of all strongly connected components in the directed graph g.
WeakComponents[g] gives a list of all weakly connected components in the undirected graph g.
ClusterSplit[c, n] splits the cluster c into n clusters.
MultivariateMedianDeviation[matrix] gives the median Euclidean distance from the median of the elements in matrix.
