# Module Bigarray.Array0

    module Array0: sig .. end

Zero-dimensional arrays. The `Array0` structure provides operations similar to those of `Bigarray.Genarray`, but specialized to the case of zero-dimensional arrays that only contain a single scalar value. Statically knowing the number of dimensions of the array allows faster operations, and more precise static type-checking.

    type (!'a, !'b, !'c) t

The type of zero-dimensional Bigarrays whose elements have OCaml type `'a`, representation kind `'b`, and memory layout `'c`.

    val create : ('a, 'b) Bigarray.kind ->
           'c Bigarray.layout -> ('a, 'b, 'c) t

`Array0.create kind layout` returns a new Bigarray of zero dimension. `kind` and `layout` determine the array element kind and the array layout as described for `Bigarray.Genarray.create`.

    val init : ('a, 'b) Bigarray.kind ->
           'c Bigarray.layout -> 'a -> ('a, 'b, 'c) t

`Array0.init kind layout v` behaves like `Array0.create kind layout` except that the element is additionally initialized to the value `v`.

    val kind : ('a, 'b, 'c) t -> ('a, 'b) Bigarray.kind

Return the kind of the given Bigarray.

    val layout : ('a, 'b, 'c) t -> 'c Bigarray.layout

Return the layout of the given Bigarray.

    val change_layout : ('a, 'b, 'c) t ->
           'd Bigarray.layout -> ('a, 'b, 'd) t

`Array0.change_layout a layout` returns a Bigarray with the specified `layout`, sharing the data with `a`. No copying of elements is involved: the new array and the original array share the same storage space.

- Since 4.06

    val size_in_bytes : ('a, 'b, 'c) t -> int

`size_in_bytes a` is `a`'s `Bigarray.kind_size_in_bytes`.

    val get : ('a, 'b, 'c) t -> 'a

`Array0.get a` returns the only element in `a`.

    val set : ('a, 'b, 'c) t -> 'a -> unit

`Array0.set a x v` stores the value `v` in `a`.

    val blit : ('a, 'b, 'c) t -> ('a, 'b, 'c) t -> unit

Copy the first Bigarray to the second Bigarray. See `Bigarray.Genarray.blit` for more details.

    val fill : ('a, 'b, 'c) t -> 'a -> unit

Fill the given Bigarray with the given value. See `Bigarray.Genarray.fill` for more details.

    val of_value : ('a, 'b) Bigarray.kind ->
           'c Bigarray.layout -> 'a -> ('a, 'b, 'c) t

Build a zero-dimensional Bigarray initialized from the given value.
