What is "multidimensional array"

n. 1 (context programming English) A data structure consisting of a vector of vectors, in the case of a 2-dimensional array, or, in the case of an N-dimensional array, a vector of multidimensional arrays of degree N minus 1, thereby allowing the simulation of a N-dimensional grid of storage locations using an underlying memory architecture in which storage is addressed in a linear fashion. 2 (context programming English) A data structure that has the semantics of an array of arrays, all of which may be indexed with values of any data type, usually with a supporting syntax built-into a programming language. 3 (context programming English) Any abstraction, usually a memory-resident data structure, that addresses storage locations via an N-dimensional coordinate space.
