  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    Functions involving two or more variables require multidimensional array indexing techniques. The latter case may thus employ a two-dimensional array of power[x][y] to replace a function to calculate x y for a limited range of x and y values. Functions that have more than one result may be implemented with lookup tables that are arrays of ...

  3. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    Function overloading is usually associated with statically-typed programming languages that enforce type checking in function calls. An overloaded function is a set of different functions that are callable with the same name. For any particular call, the compiler determines which overloaded function to use and resolves this at compile time ...

  4. List of mathematical functions - Wikipedia

    Thomae's function: is a function that is continuous at all irrational numbers and discontinuous at all rational numbers. It is also a modification of Dirichlet function and sometimes called Riemann function. Kronecker delta function: is a function of two variables, usually integers, which is 1 if they are equal, and 0 otherwise.

  5. List of multiple discoveries - Wikipedia

    en.wikipedia.org/wiki/List_of_multiple_discoveries

    Merton believed that it is multiple discoveries, rather than unique ones, that represent the common pattern in science. [5] Merton contrasted a "multiple" with a "singleton"—a discovery that has been made uniquely by a single scientist or group of scientists working together. [6] The distinction may blur as science becomes increasingly ...

  6. Recursion (computer science) - Wikipedia

    en.wikipedia.org/wiki/Recursion_(computer_science)

    Recursion that contains only a single self-reference is known as single recursion, while recursion that contains multiple self-references is known as multiple recursion. Standard examples of single recursion include list traversal, such as in a linear search, or computing the factorial function, while standard examples of multiple recursion ...

  7. Aggregate function - Wikipedia

    en.wikipedia.org/wiki/Aggregate_function

    The input and output domains may be the same, such as for SUM, or may be different, such as for COUNT. Aggregate functions occur commonly in numerous programming languages, in spreadsheets, and in relational algebra. The listagg function, as defined in the SQL:2016 standard [2] aggregates data from multiple rows into a single concatenated string.

    Actors who play a character with multiple names and/or a secret identity (e.g. superheroes); Actors who play multiple copies of a single character (e.g. Vittorio Gassman and Don Adams [as St. Sauvage and Maxwell Smart, respectively] in The Nude Bomb, Hugo Weaving as Agent Smith in The Matrix series, and Tom Cruise in Oblivion);

  9. Static single-assignment form - Wikipedia

    en.wikipedia.org/wiki/Static_single-assignment_form

    The name Φ-function was chosen by Rosen to be a more publishable version of "phony function". [3] Alpern, Wegman, and Zadeck presented another optimization, but using the name "static single assignment". [7] Finally, in 1989, Rosen, Wegman, Zadeck, Cytron, and Ferrante found an efficient means of converting programs to SSA form. [8]
