Definizione monolingua

parameter

parameter (plural parameters)

1. (mathematics, physics) A variable kept constant during an experiment, calculation or similar.
2. (programming) A name in a function or subroutine definition that is replaced by, or bound to, the corresponding actual argument when the function or subroutine is called: a formal parameter.

   Roughly, a tuple of arguments could be thought of as a vector, whereas a tuple of parameters could be thought of as a covector (i.e., linear functional). When a function is called, a parameter tuple becomes ""bound"" to an argument tuple, allowing the function instance itself to be computed to yield a return value. This would be roughly analogous to applying a covector to a vector (by taking their dot product (or, rather, matrix-product of row vector and column vector)) to obtain a scalar.

3. (programming) The value which is passed into the function to instantiate such a name; the argument or actual parameter.
4. A characteristic or feature that distinguishes something from others
