Official release 4.12.1
IN THIS PACKAGE
Module Bigarray . Array0
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 ) kind -> 'c 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 Genarray.create.

val init : ( 'a, 'b ) kind -> 'c 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.

  • since 4.12.0
val kind : ( 'a, 'b, 'c ) t -> ( 'a, 'b ) kind

Return the kind of the given Bigarray.

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

Return the layout of the given Bigarray.

val change_layout : ( 'a, 'b, 'c ) t -> 'd 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 4.06.0
val size_in_bytes : ( 'a, 'b, 'c ) t -> int

size_in_bytes a is a's 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 Genarray.blit for more details.

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

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

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

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