either-or function
51Z function — In mathematics, the Z function is a function used for studying the Riemann zeta function along the critical line where the real part of the argument is one half. It is also called the Riemann Siegel Z function, the Riemann Siegel zeta function,… …
52Polynomial and rational function modeling — In statistical modeling (especially process modeling), polynomial functions and rational functions are sometimes used as an empirical technique for curve fitting.Polynomial function modelsA polynomial function is one that has the form:y = a… …
53Domain of a function — Venn diagram showing f, a function from domain X to codomain Y. The smaller oval inside Y is the image of f, sometimes called the range of f. In mathematics, the domain of definition or simply the domain of a function is the set of input or… …
54μ-recursive function — In mathematical logic and computer science, the μ recursive functions are a class of partial functions from natural numbers to natural numbers which are computable in an intuitive sense. In fact, in computability theory it is shown that the μ… …
55Continuous function (topology) — In topology and related areas of mathematics a continuous function is a morphism between topological spaces. Intuitively, this is a function f where a set of points near f(x) always contain the image of a set of points near x . For a general… …
56Minkowski's question mark function — Minkowski question mark function. ?(x) is on the left and ?(x) x is on the right. In …
57Chebyshev function — The Chebyshev function ψ(x), with x < 50 The function ψ( …
58Green's function (many-body theory) — In many body theory, the term Green s function (or Green function) is sometimes used interchangeably with correlation function, but refers specifically to correlators of field operators or creation and annihilation operators.The name comes from… …
59Size function — Size functions are shape descriptors, in a geometrical/topological sense. They are functions from the half plane to the natural numbers, counting certain connected components of a topological space. They are used in pattern recognition and… …
60Main function — See also: Entry point In many programming languages, the main function is where a program starts execution. It is responsible for the high level organization of the program s functionality, and typically has access to the command arguments given… …
