In mathematics, a partial function f from a set X to a set Y is a function from a subset S of X (possibly the whole X itself) to Y. The subset S, that...

partial application (or partial function application) refers to the process of fixing a number of arguments of a function, producing another function...

In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held...

computer science, a general recursive function, partial recursive function, or μ-recursive function is a partial function from natural numbers to natural numbers...

non-empty open interval. Such a function is then called a partial function. A function f on a set S means a function from the domain S, without specifying...

In time series analysis, the partial autocorrelation function (PACF) gives the partial correlation of a stationary time series with its own lagged values...

For example, one can formalize computable functions as μ-recursive functions, which are partial functions that take finite tuples of natural numbers...

partial differential equation (PDE) is an equation which involves a multivariable function and one or more of its partial derivatives. The function is...

first-class functions if it treats functions as first-class citizens. This means the language supports passing functions as arguments to other functions, returning...

one-to-one correspondence generalizes to partial functions, where they are called partial bijections, although partial bijections are only required to be injective...

nonzero s ∈ F . {\displaystyle s\in F.} A homogeneous function f from V to W is a partial function from V to W that has a linear cone C as its domain, and...

as, partial application. The example above can be used to illustrate partial application; it is quite similar. Partial application is the function apply...

function may refer to: Recursive function (programming), a function which references itself General recursive function, a computable partial function...

of a function, with the other variables held constant ∂, a symbol that can denote a partial derivative, sometimes pronounced "partial dee" Partial differential...

zero function; however note that the partial derivatives are not uniformly convergent to the zero function (the derivative of the zero function). This...

under a mild condition on the partial derivatives, the set of zeros of a system of equations is locally the graph of a function. Augustin-Louis Cauchy (1789–1857)...

series associated with a periodic function converges to the function. The n-th partial sum of the Fourier series of a function f of period 2π is defined by...

function y(x) is given by: §11.5  d y d x = − ∂ R ∂ x ∂ R ∂ y = − R x R y , {\displaystyle {\frac {dy}{dx}}=-{\frac {\,{\frac {\partial R}{\partial x}}\...

is not a function but a partial function, then f {\displaystyle f} is called a partial binary operation. For instance, division is a partial binary operation...

In many contexts, a partial function is called simply a function, and its natural domain is called simply its domain. The function f {\displaystyle f}...

derivative of the function can be written as f ′ ( z ) = ∂ u ∂ x + i ∂ v ∂ x = ∂ v ∂ y − i ∂ u ∂ y {\displaystyle f'(z)={\frac {\partial u}{\partial x}}+i{\frac...

matrix of second-order partial derivatives of a scalar-valued function, or scalar field. It describes the local curvature of a function of many variables....

notion of transformation is generalized to partial functions, then a partial transformation is a function f: A → B, where both A and B are subsets of...

expressions like sin−1(x) to denote the inverse of the sine function applied to x (actually a partial inverse; see below). Other authors feel that this may...

{\displaystyle {\frac {\partial f}{\partial x}}=2x+y,\qquad {\frac {\partial f}{\partial y}}=x+2y.} In general, the partial derivative of a function f ( x 1 , … ...

functions are partial functions that have a domain formed by all real numbers, except some isolated points. Examples include the reciprocal function x...

Function composition appears in one form or another in numerous programming languages. Partial composition is possible for multivariate functions. The...
