LeastSquares[m, b] finds an x that solves the linear least-squares problem for the matrix equation m.x == b.
Listable is an attribute that can be assigned to a symbol f to indicate that the function f should automatically be threaded over lists that appear as its arguments.
LogGamma[z] gives the logarithm of the gamma function log \[CapitalGamma](z).
LucasL
(Built-in Mathematica Symbol) LucasL[n] gives the Lucas number L_n.LucasL[n, x] gives the Lucas polynomial L_n (x).
Mod
(Built-in Mathematica Symbol) Mod[m, n] gives the remainder on division of m by n. Mod[m, n, d] uses an offset d.
NevilleThetaD[z, m] gives the Neville theta function \[CurlyTheta]_d (z \[VerticalSeparator] m).
NevilleThetaN[z, m] gives the Neville theta function \[CurlyTheta]_n (z \[VerticalSeparator] m).
NevilleThetaS[z, m] gives the Neville theta function \[CurlyTheta]_s (z \[VerticalSeparator] m).
QBinomial[n, m, q] gives the q-binomial coefficient (n; m)_q.
RootSum
(Built-in Mathematica Symbol) RootSum[f, form] represents the sum of form[x] for all x that satisfy the polynomial equation f[x] == 0.
