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 t('a, 'b, 'c);
The type of zero-dimensional Bigarrays whose elements have
OCaml type 'a
, representation kind 'b
, and memory layout 'c
.
let create: (Bigarray.kind('a, 'b), Bigarray.layout('c)) => t('a, 'b, 'c);
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
.
let init: (Bigarray.kind('a, 'b), Bigarray.layout('c), 'a) => t('a, 'b, 'c);
Array0.init kind layout v
behaves like Array0.create kind layout
except that the element is additionally initialized to the value v
.
let kind: t('a, 'b, 'c) => Bigarray.kind('a, 'b);
Return the kind of the given Bigarray.
let layout: t('a, 'b, 'c) => Bigarray.layout('c);
Return the layout of the given Bigarray.
let change_layout: (t('a, 'b, 'c), Bigarray.layout('d)) => t('a, 'b, 'd);
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.
let size_in_bytes: t('a, 'b, 'c) => int;
size_in_bytes a
is a
's Bigarray.kind_size_in_bytes
.
let get: t('a, 'b, 'c) => 'a;
Array0.get a
returns the only element in a
.
let set: (t('a, 'b, 'c), 'a) => unit;
Array0.set a x v
stores the value v
in a
.
let blit: (t('a, 'b, 'c), t('a, 'b, 'c)) => unit;
Copy the first Bigarray to the second Bigarray.
See Bigarray.Genarray.blit
for more details.
let fill: (t('a, 'b, 'c), 'a) => unit;
Fill the given Bigarray with the given value.
See Bigarray.Genarray.fill
for more details.
let of_value:
(Bigarray.kind('a, 'b), Bigarray.layout('c), 'a) => t('a, 'b, 'c);
Build a zero-dimensional Bigarray initialized from the given value.
