Documentation¶

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 Memory mapping of a file as a one-dimensional big array. See Bigarray.Genarray.map_file for more details. 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.
