one-variable function
91Green's function — In mathematics, Green s function is a type of function used to solve inhomogeneous differential equations subject to boundary conditions. The term is used in physics, specifically in quantum field theory and statistical field theory, to refer to… …
92Main function (programming) — In some programming languages, the main function is where a program starts execution. It is generally the first user written function run when a program starts (some system specific software generally runs before the main function), though some… …
93Global variable — In computer programming, a global variable is a variable that is accessible in every scope. Interaction mechanisms with global variables are called global environment (see also global state) mechanisms. The global environment paradigm is… …
94Correlation function — For other uses, see Correlation function (disambiguation). A correlation function is the correlation between random variables at two different points in space or time, usually as a function of the spatial or temporal distance between the points.… …
95Local hidden variable theory — In quantum mechanics, a local hidden variable theory is one in which distant events are assumed to have no instantaneous (or at least faster than light) effect on local ones. According to the quantum entanglement theory of quantum mechanics, on… …
96Hash function — A hash function is any well defined procedure or mathematical function for turning some kind of data into a relatively small integer, that may serve as an index into an array. The values returned by a hash function are called hash values, hash… …
97Riemann zeta function — ζ(s) in the complex plane. The color of a point s encodes the value of ζ(s): dark colors denote values close to zero and hue encodes the value s argument. The white spot at s = 1 is the pole of the zeta function; the black spots on the… …
98C variable types and declarations — The C programming language has an extensive system for declaring variables of different types. The rules for the more complex types can be confusing at times, due to the decisions taken over their design. The principal decision is that the… …
99Heaviside step function — The Heaviside step function, H , also called the unit step function, is a discontinuous function whose value is zero for negative argument and one for positive argument.It seldom matters what value is used for H (0), since H is mostly used as a… …
100Implicit function — In mathematics, an implicit function is a generalization for the concept of a function in which the dependent variable has not been given explicitly in terms of the independent variable. To give a function f explicitly is to provide a… …
