module Array1: sig .. end
One-dimensional arrays. The Array1 structure provides operations
similar to those of
Bigarray.Genarray, but specialized to the case of one-dimensional arrays.
(The Array2 and Array3 structures below provide operations
specialized for two- and three-dimensional arrays.)
Statically knowing the number of dimensions of the array allows
faster operations, and more precise static type-checking.
type ('a, 'b, 'c) t
The type of one-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 -> int -> ('a, 'b, 'c) t
Array1.create kind layout dim returns a new bigarray of
one dimension, whose size is dim. kind and layout
determine the array element kind and the array layout
as described for Genarray.create.
val dim : ('a, 'b, 'c) t -> int
Return the size (dimension) of the given one-dimensional
big array.
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 get : ('a, 'b, 'c) t -> int -> 'a
Array1.get a x, or alternatively a.{x},
returns the element of a at index x.
x must be greater or equal than 0 and strictly less than
Array1.dim a if a has C layout. If a has Fortran layout,
x must be greater or equal than 1 and less or equal than
Array1.dim a. Otherwise, Invalid_argument is raised.
val set : ('a, 'b, 'c) t -> int -> 'a -> unit
Array1.set a x v, also written
a.{x} <- v,
stores the value
v at index
x in
a.
x must be inside the bounds of
a as described in
Bigarray.Array1.get;
otherwise,
Invalid_argument is raised.
val sub : ('a, 'b, 'c) t ->
int -> int -> ('a, 'b, 'c) t
Extract a sub-array of the given one-dimensional big array.
See Genarray.sub_left for more details.
val blit : ('a, 'b, 'c) t -> ('a, 'b, 'c) t -> unit
Copy the first big array to the second big array.
See Genarray.blit for more details.
val fill : ('a, 'b, 'c) t -> 'a -> unit
Fill the given big array with the given value.
See Genarray.fill for more details.
val of_array : ('a, 'b) Bigarray.kind ->
'c Bigarray.layout -> 'a array -> ('a, 'b, 'c) t
Build a one-dimensional big array initialized from the
given array.
val map_file : Unix.file_descr ->
?pos:int64 ->
('a, 'b) Bigarray.kind ->
'c Bigarray.layout -> bool -> int -> ('a, 'b, 'c) t
val unsafe_get : ('a, 'b, 'c) t -> int -> 'a
Like
Bigarray.Array1.get, but bounds checking is not always performed.
Use with caution and only when the program logic guarantees that
the access is within bounds.
val unsafe_set : ('a, 'b, 'c) t -> int -> 'a -> unit
Like
Bigarray.Array1.set, but bounds checking is not always performed.
Use with caution and only when the program logic guarantees that
the access is within bounds.
