  2. Row- and column-major order - Wikipedia

    en.wikipedia.org/wiki/Row-_and_column-major_order

    To use column-major order in a row-major environment, or vice versa, for whatever reason, one workaround is to assign non-conventional roles to the indexes (using the first index for the column and the second index for the row), and another is to bypass language syntax by explicitly computing positions in a one-dimensional array.

  3. Move-to-front transform - Wikipedia

    en.wikipedia.org/wiki/Move-to-front_transform

    The move-to-front (MTF) transform is an encoding of data (typically a stream of bytes) designed to improve the performance of entropy encoding techniques of compression. When efficiently implemented, it is fast enough that its benefits usually justify including it as an extra step in data compression algorithm .

  4. Map (higher-order function) - Wikipedia

    en.wikipedia.org/wiki/Map_(higher-order_function)

    This is the original definition for maplist, mapping a function over successive rest lists: maplist[x;f] = [null[x] -> NIL;T -> cons[f[x];maplist[cdr[x];f]]] The function maplist is still available in newer Lisps like Common Lisp, [5] though functions like mapcar or the more generic map would be preferred.

  5. Self-organizing list - Wikipedia

    en.wikipedia.org/wiki/Self-organizing_list

    Move-to-front (or 'Move to top') - places frequently used, or recently used, information is at the top so it can be found quickly, without having to traverse the whole list. Self-learning Frequency list (or 'Order by access frequency') - re-arranges a list of options in a GUI menu, so that the top ones are the options most commonly selected by ...

  6. Array (data structure) - Wikipedia

    en.wikipedia.org/wiki/Array_(data_structure)

    Arrays can have multiple dimensions, thus it is not uncommon to access an array using multiple indices. For example, a two-dimensional array A with three rows and four columns might provide access to the element at the 2nd row and 4th column by the expression A[1][3] in the case of a zero-based indexing

  7. Iterated function - Wikipedia

    en.wikipedia.org/wiki/Iterated_function

    In mathematics, an iterated function is a function that is obtained by composing another function with itself two or several times. The process of repeatedly applying the same function is called iteration. In this process, starting from some initial object, the result of applying a given function is fed again into the function as input, and ...

  8. Special member functions - Wikipedia

    en.wikipedia.org/wiki/Special_member_functions

    In the C++ programming language, special member functions [1] are functions which the compiler will automatically generate if they are used, but not declared explicitly by the programmer. The automatically generated special member functions are:

  9. Systolic array - Wikipedia

    en.wikipedia.org/wiki/Systolic_array

    At this point, the result of the multiplication is stored in the array and can now be output a row or a column at a time, flowing down or across the array. [4] Systolic arrays are arrays of DPUs which are connected to a small number of nearest neighbour DPUs in a mesh-like topology. DPUs perform a sequence of operations on data that flows ...
