Module Sundials_RealArray

module Sundials_RealArray: sig .. end

Arrays of flaoting-point values.

type t = (float, Stdlib.Bigarray.float64_elt, Stdlib.Bigarray.c_layout)
       Stdlib.Bigarray.Array1.t

A Bigarray of floats.

val make : int -> float -> t

make n x returns an array with n elements each set to x.

val create : int -> t

create n returns an uninitialized array with n elements.

val empty : t

An array with no elements.

val get : t -> int -> float

get a i returns the ith element of a.

val set : t -> int -> float -> unit

set a i v sets the ith element of a to v.

val init : int -> (int -> float) -> t

init n f returns an array with n elements, with element i set to f i.

val pp : Stdlib.Format.formatter -> t -> unit

Pretty-print an array using the Format module.

val ppi : ?start:string ->
       ?stop:string ->
       ?sep:string ->
       ?item:(Stdlib.Format.formatter -> int -> float -> unit) ->
       unit -> Stdlib.Format.formatter -> t -> unit

Pretty-print an array using the Format module. The defaults are: start="[", stop="]", sep=" ", and item=fun f->Format.fprintf f "%2d=% -15e" (see fprintf).

val of_array : float array -> t

Creates an array by copying the contents of a float array.

val of_list : float list -> t

Creates an array by copying the contents of a float list.

val to_array : t -> float array

Copies into a new float array.

val into_array : t -> float array -> unit

Copies into an existing float array.

val to_list : t -> float list

Copies into a float list.

val copy : t -> t

Creates a new array with the same contents as an existing one.

val sub : t -> int -> int -> t

Access a sub-array of the given array without copying.

val blitn : src:t ->
       ?spos:int -> dst:t -> ?dpos:int -> int -> unit

blitn ~src ?spos ~dst ?dpos len copies len elements of src at offset spos to dst at offset dpos. The spos and dpos arguments are optional and default to zero.

Raises Invalid_argument "RealArray.nblit" if spos, dpos, and len do not specify valid subarrays of src and dst.

val blit : src:t -> dst:t -> unit

Copy the first array into the second one. See Bigarray.Genarray.blit for more details.

val fill : t -> ?pos:int -> ?len:int -> float -> unit

fill a c sets elements of a to the constant c. The elements from pos to pos + len - 1 are set to the constant, with pos defaulting to 0 and len to the length of the array.

val length : t -> int

Returns the length of an array.

val fold_left : ('a -> float -> 'a) -> 'a -> t -> 'a

fold_left f b a returns f (f (f b a.{0}) a.{1}) ...).

val fold_right : (float -> 'a -> 'a) -> t -> 'a -> 'a

fold_right f b a returns (f ... (f a.{n-2} (f a.{n-1} b))).

val iter : (float -> unit) -> t -> unit

iter f a successively applies f to the elements of a.

val iteri : (int -> float -> unit) -> t -> unit

iteri f a successively applies f to the indexes and values of a.

val map : (float -> float) -> t -> unit

map f a replaces each element a.{i} with f a.{i}.

val mapi : (int -> float -> float) -> t -> unit

map f a replaces each element a.{i} with f i a.{i}.
