Array

An array is a systematic arrangement of similar objects, usually in rows and columns.

Things called an array include:

Music

• In twelve-tone and serial composition, the presentation of simultaneous twelve-tone sets such that the sums of their horizontal segments form a succession of twelve-tone aggregates
• Array mbira, a musical instrument
• Spiral array model, a music pitch space

Science

Astronomy

A telescope array, also called astronomical interferometer, such as the:

• 4C Array
• Akeno Giant Air Shower Array (AGASA)
• Allen Telescope Array (ATA), formerly known as the One Hectare Telescope (1hT)
• Antarctic Muon And Neutrino Detector Array (AMANDA)
• Atacama Large Millimeter Array (ALMA)
• Australia Telescope Compact Array
• CHARA array
• Cherenkov Telescope Array (CTA)
• Chicago Air Shower Array (CASA)
• Infrared Optical Telescope Array (IOTA)
• Interplanetary Scintillation Array (IPS array) also called the Pulsar Array
• LOFAR (LOw Frequency ARray)
• Modular Neutron Array (MoNA)
• Murchison Widefield Array (MWA)
• Nuclear Spectroscopic Telescope Array (NuSTAR)
• Square Kilometre Array (SKA)
• Submillimeter Array (SMA)
• Sunyaev-Zel'dovich Array (SZA)
• Telescope Array Project
• Very Large Array (VLA)
• Very Long Baseline Array (VLBA)

Biology

• Various kinds of multiple biological arrays called microarrays
• Visual feature array, a model for the visual cortex

Computer science

Generally, a collection of same type 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 composed of key-value pairs, often implemented as a hash table or search tree

or various kinds of the above, such as:

• Bit array or bit vector
• Dynamic array, allocated at run time
• Jagged array, a multidimensional array where the rows have different lengths individually
• 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

or various related concepts:

• Array programming, using matrix algebra notation in programs (not the same as array processing)
• Array slicing, the extraction of sub-arrays of an array

or also:

• Global Arrays, a library for parallel processing
• Intel Array Visualizer, a piece of scientific graphics software

Mathematics and statistics

• A standard array in coding theory
• An array or matrix (mathematics)
  • a Costas array
  • a Monge array
• A holor
• Intersection array a concept of category theory
