An '''array''' is a systematic arrangement of objects, usually in rows and columns. Specifically, it may refer to: |
|||
== In computer science == |
|||
Generally, a collection of data items that can be selected by indices computed at run-time, including: |
|||
* [[Array data structure]], an arrangement of items at equally spaced addresses in computer memory |
|||
* [[Array data type]], used in a programming language to specify a variable that can be indexed |
|||
* [[Associative array]], an abstract data structure model that generalizes arrays to arbitrary indices |
|||
or various kinds of the above, such as |
|||
* [[Bit array]] or bit vector |
|||
* [[Dynamic array]], allocated at run time |
|||
* [[Parallel array]] of records, with each field stored as a separate array |
|||
* [[Sparse array]], with most elements omitted, to store a sparse matrix |
|||
* [[Variable-length array]] |
|||
* [[Jagged array]], where the rows have different lengths individually |
|||
or various related concepts: |
|||
* [[Vector processor|Array processor]], a computer to process arrays of data (not to be confused with a processor array) |
|||
* [[Array programming]], using matrix algebra notation in programs (not the same as array processing) |
|||
* [[Array slicing]], the extraction of sub-arrays of an array |
|||
* [[APL (programming language)]] |
|||
or also: |
|||
* [[Video Graphics Array]] (VGA), a display adapter and video format, and many variants thereof (EVGA, FWVGA, QVGA, QXGA, SVGA, SXGA, SXGA+, TXGA, UVGA, XGA, XGA+, ...) |
|||
<!-- Probably not worth putting here: |
|||
* [[Global array]], a library for parallel processing |
|||
* [[Intel Array Visualizer]], a scientific graphics software |
|||
* [[ICL Distributed Array Processor]], an array processor for the ICL --> |
|||
== In mathematics and statistics == |
|||
* An array or [[matrix (mathematics)]] ''e.g.'' a [[Monge array]], a [[Costas array]] |
|||
* A [[standard array]] in coding theory |
|||
* In statistics, arrays are a name for some kinds of [[:Category:Experimental design]] |
|||
* [[Intersection array]] a concept of category theory |
|||
* The [[thinned array curse]] or sparse array curse, a theorem about elecromagnetic waves |
|||

|||
* An antenna array, such as a [[phased array]], a [[tower array]], etc. |
|||
* A speaker array, used to produce [[directional Sound]] |
