Functional

 

a mathematical concept originating in the calculus of variations, where it denotes a variable that depends on one or more functions or curves. Examples of functionals are the area bounded by a closed curve of a given length and the work of a force field along a curve. As functional analysis developed, the term “functional” acquired the more general sense of a numbervalued function defined on a linear space.
