Bigarray.Array0 - Zero-dimensional arrays.
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.
Since 4.05.0
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 .
Since 4.12.0
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 4.06.0
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.
