LibraryUnload[lib] unloads all functions that have been loaded from a Wolfram Library, then it unloads the library.
Off
(Built-in Mathematica Symbol) Off[symbol::tag] switches off a message, so that it is no longer printed. Off["name"] switches off a named group of messages.Off[s] switches off tracing messages associated ...
EllipticTheta[a, u, q] gives the theta function \[CurlyTheta]_a (u, q) (a = 1, ..., 4).
PolyLog
(Built-in Mathematica Symbol) PolyLog[n, z] gives the polylogarithm function Li_n (z).PolyLog[n, p, z] gives the Nielsen generalized polylogarithm function S n, p (z).
Wronskian[{y_1, y_2, ...}, x] gives the Wronskian determinant for the functions y_1, y_2, ... depending on x.Wronskian[eqn, y, x] gives the Wronskian determinant for the ...
Limit[expr,x->x_0] tells you what the value of expr is when x tends to x_0. When this value is infinite, it is often useful instead to know the residue of expr when x equals ...
FindLibrary[lib] finds a dynamic library that can be loaded by LibraryFunctionLoad.
DivisorSum[n, form] represents the sum of form[i] for all i that divide n.DivisorSum[n, form, cond] includes only those divisors for which cond[i] gives True.
Numerical sums, products and integrals. Here is a numerical approximation to ∑_(i=1)^∞((1)/(i^3)). NIntegrate can handle singularities in the integration region.
$LibraryPath gives the default list of directories to search in attempting to find a library.
