Alternative forms
* parametreNoun
(en noun)- 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.
- The parameter of the principal axis of a conic section is called the latus rectum.
Usage notes
* (the value used to instantiate the name) Some authors regard use of parameter'' to mean ''argument'' as imprecise, preferring that ''parameter'' refers only to the name that will be instantiated, and ''argument to refer to the value that will be supplied to it at runtime.Synonyms
