| − | Arrays may be single-dimensional, or mutli-dimensional (aka poly-dimensional). A 2-dimensional array with data consisting of numbers can be thought of as a form of mathematical '''Matrix'''. Although implementations vary, a multi-dimensional array can be conceptualized as an array of other arrays. For instance, a 3-dimensional array could be accessed as | + | Arrays may be single-dimensional, or mutli-dimensional (aka poly-dimensional).
