CopulaDistribution[ker, {dist_1, dist_2, ...}] represents a copula distribution with kernel distribution ker and marginal distributions dist_1, dist_2, ....
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 ...
Mathematica automatically handles both numeric and symbolic matrices, seamlessly switching among large numbers of highly-optimized algorithms. Using many original methods, ...
AlgebraicIntegerQ[a] yields True if a is an algebraic integer, and yields False otherwise.
AlgebraicNumberNorm[a] gives the norm of the algebraic number a.
Apart
(Built-in Mathematica Symbol) Apart[expr] rewrites a rational expression as a sum of terms with minimal denominators. Apart[expr, var] treats all variables other than var as constants.
LiftingFilterData[...] represents lifting-filter data used to compute forward and inverse lifting wavelet transforms.
MaxIterations is an option that specifies the maximum number of iterations that should be tried in various built-in functions and algorithms.
PolynomialMod[poly, m] gives the polynomial poly reduced modulo m. PolynomialMod[poly, {m_1, m_2, ...}] reduces modulo all of the m_i.
RootOfUnityQ[a] yields True if a is a root of unity, and yields False otherwise.
