undefined function
1Undefined variable — An undefined variable in the source code of a computer program is a variable that is accessed in the code but has not been previously declared by that code.In some programming languages an implicit declaration is provided the first time such a… …
2Undefined behavior — In computer programming, undefined behavior is a feature of some programming languages most famously C.[1] In these languages, to simplify the specification and allow some flexibility in implementation, the specification leaves the results of… …
3Μ-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… …
4Partial function — Not to be confused with partial function of a multilinear map. An example of a partial function that is not a total function …
5μ-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… …
6Defined and undefined — In mathematics, defined and undefined are used to explain whether or not expressions have meaningful, sensible, and unambiguous values. Not all branches of mathematics come to the same conclusion.Examples and workaroundsThe following expressions… …
7Rational function — In mathematics, a rational function is any function which can be written as the ratio of two polynomial functions. DefinitionsIn the case of one variable, x , a rational function is a function of the form: f(x) = frac{P(x)}{Q(x)}where P and Q are …
8Gamma function — For the gamma function of ordinals, see Veblen function. The gamma function along part of the real axis In mathematics, the gamma function (represented by the capital Greek letter Γ) is an extension of the factorial function, with its… …
9Hash 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… …
10Computable function — Total recursive function redirects here. For other uses of the term recursive function , see Recursive function (disambiguation). Computable functions are the basic objects of study in computability theory. Computable functions are the formalized …
