Gamma
(Built-in Mathematica Symbol) Gamma[z] is the Euler gamma function \[CapitalGamma](z). Gamma[a, z] is the incomplete gamma function \[CapitalGamma](a, z). Gamma[a, z_0, z_1] is the generalized incomplete ...
GammaRegularized[a, z] is the regularized incomplete gamma function Q(a, z).
GatherBy[list, f] gathers into sublists each set of elements in list that gives the same value when f is applied.GatherBy[list, {f_1, f_2, ...}] gathers list into nested ...
IntegerPart[x] gives the integer part of x.
InverseFourier[list] finds the discrete inverse Fourier transform of a list of complex numbers.
Labeled
(Built-in Mathematica Symbol) Labeled[expr, lbl] displays expr labeled with lbl. Labeled[expr, lbl, pos] places lbl at a position specified by pos. Labeled[expr, {lbl_1, lbl_2, ...}, {pos_1, ...}] places ...
LinearSolve[m, b] finds an x which solves the matrix equation m.x == b. LinearSolve[m] generates a LinearSolveFunction[...] which can be applied repeatedly to different b.
Line
(Built-in Mathematica Symbol) Line[{pt_1, pt_2, ...}] is a graphics primitive that represents a line joining a sequence of points. Line[{{pt_11, pt_12, ...}, {pt_21, ...}, ...}] represents a collection of ...
