Bigarray.Array0 - Zero-dimensional arrays.

Module

Module Bigarray.Array0

Documentation

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.

Since 4.05.0

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

The type of zero-dimensional big arrays 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 kind : ('a, 'b, 'c) t -> ('a, 'b) Bigarray.kind

Return the kind of the given big array.

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

Return the layout of the given big array.

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 big array to the second big array. See Bigarray.Genarray.blit for more details.

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

Fill the given big array 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 big array initialized from the given value.
