Module `Bigarray.Array0`Source

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.

Sourcetype ((!'a : any), (!'b : any), (!'c : any)) t : mutable_data

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

Source

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

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.

Source

val init : 
  ('a : value_or_null) ('b : any) ('c : any). ('a, 'b) kind ->
  'c layout ->
  'a @ local ->
  ('a, 'b, 'c) t @ unique

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

Source

val kind : 
  ('a : any) ('b : any) ('c : any). ('a, 'b, 'c) t @ immutable ->
  ('a, 'b) kind @@ stateless

Return the kind of the given Bigarray.

Source

val layout : 
  ('a : any) ('b : any) ('c : any). ('a, 'b, 'c) t @ immutable ->
  'c layout @@ stateless

Return the layout of the given Bigarray.

Source

val change_layout : 
  ('a : any) ('b : any) ('c : any). ('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

Source

val size_in_bytes : 
  ('a : any) ('b : any) ('c : any). ('a, 'b, 'c) t @ local immutable ->
  int

size_in_bytes a is a's kind_size_in_bytes.

Source

val get : 
  ('a : value_or_null) ('b : any) ('c : any). ('a, 'b, 'c) t @ local shared ->
  'a

Array0.get a returns the only element in a.

Source

val set : 
  ('a : value_or_null) ('b : any) ('c : any). ('a, 'b, 'c) t @ local ->
  'a @ local ->
  unit

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

Source

val blit : 
  ('a : any) ('b : any) ('c : any). ('a, 'b, 'c) t @ shared ->
  ('a, 'b, 'c) t ->
  unit

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

Source

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

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

Source

val of_value : 
  ('a : value_or_null) ('b : any) ('c : any). ('a, 'b) kind ->
  'c layout ->
  'a @ local ->
  ('a, 'b, 'c) t @ unique

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