For most computational purposes, arrays should contain objects of a more specific type, such as Float64 or Int32. In the most general case, an array may contain objects of type Any. Zero-dimensional arrays are allowed, see this FAQ entry. See the manual section on the AbstractArray interface for more details on implementing a custom array type.Īn array is a collection of objects stored in a multi-dimensional grid. As such, it's also possible to define custom array types by inheriting from AbstractArray. The array library is implemented almost completely in Julia itself, and derives its performance from the compiler, just like any other code written in Julia. Julia does not treat arrays in any special way. Most technical computing languages pay a lot of attention to their array implementation at the expense of other containers. Julia, like most technical computing languages, provides a first-class array implementation.
