FindCurvePath (Built-in Mathematica Symbol)

FindCurvePath[{{x_1, y_1}, {x_2, y_2}, ...}] gives an ordering of the {x_i, y_i} that corresponds to one or more smooth curves.

Round (Built-in Mathematica Symbol)

Round[x] gives the integer closest to x. Round[x, a] rounds to the nearest multiple of a.

StirlingS1 (Built-in Mathematica Symbol)

StirlingS1[n, m] gives the Stirling number of the first kind S_n^(m).

Piecewise (Built-in Mathematica Symbol)

Piecewise[{{val_1, cond_1}, {val_2, cond_2}, ...}] represents a piecewise function with values val_i in the regions defined by the conditions cond_i. Piecewise[{{val_1, ...

NevilleThetaC (Built-in Mathematica Symbol)

NevilleThetaC[z, m] gives the Neville theta function \[CurlyTheta]_c (z \[VerticalSeparator] m).

KleinInvariantJ (Built-in Mathematica Symbol)

KleinInvariantJ[\[Tau]] gives the Klein invariant modular elliptic function J(\[Tau]).

KroneckerDelta (Built-in Mathematica Symbol)

KroneckerDelta[n_1, n_2, ...] gives the Kronecker delta \[Delta] Subscript[n, 1] Subscript[n, 2] ..., equal to 1 if all the n_i are equal, and 0 otherwise.

LogIntegral (Built-in Mathematica Symbol)

LogIntegral[z] is the logarithmic integral function li(z).

Fit (Built-in Mathematica Symbol)

Fit[data, funs, vars] finds a least-squares fit to a list of data as a linear combination of the functions funs of variables vars.
